Finding the right app to book flight tickets can save you hundreds of dollars and hours of frustration. The travel market is crowded with options, each claiming to be the cheapest or easiest. Most of them are useful. Some genuinely excel at specific things. This guide cuts through the noise and shows you exactly which apps work best for different situations.
The goal here is simple. You need to book a flight. You want the best price, a smooth experience, and customer support if something goes wrong. I’ll walk you through the best apps available today, explain what makes each one special, and help you choose the right one for your next trip.
What Makes a Good Flight Booking App?
Before diving into specific apps, let’s establish what actually matters when you’re booking flights.
Key Features to Look For
Price Comparison Accuracy
The app should show real-time prices from multiple airlines. Outdated pricing means you waste time on flights that are no longer available at that price.
Booking Speed
A good app lets you complete a booking in under two minutes. Slow checkout processes cause people to abandon purchases.
Filter Options
You need to sort by price, time, airline, stops, and duration. Without these filters, you’re manually scanning hundreds of flights.
Refund and Change Policies
The app should clearly display cancellation and modification rules before you buy. Hidden fees destroy trust.
Customer Support
When something goes wrong (and it sometimes does), you need to reach a human. Check whether the app offers chat, email, or phone support.
User Interface Design
Confusing layouts waste time. Good apps have clean designs that guide you through the process naturally.
Mobile Experience
Since most people book on phones, the app should work smoothly on mobile without crashing or freezing.
The Best Apps to Book Flight Tickets in 2024
Google Flights
What It Does
Google Flights is one of the most powerful flight search tools available. It searches across multiple airlines and booking sites in seconds.
Why It Stands Out
Google Flights doesn’t actually book flights. Instead, it shows you prices from various booking platforms and airlines, then sends you to the official website or third-party sellers. This transparency is valuable because you see exactly where you’re booking.
The app includes features that few competitors offer:
- Price tracking that alerts you when fares drop
- Flexible date search showing price differences across weeks
- Route explorer that lets you discover cheap flights to various destinations
- Calendar view comparing prices day by day
Best For
People who want to explore options and get the lowest possible price. If you’re flexible on dates, this app saves significant money.
How to Use It Effectively
Open Google Flights and enter your departure city and destination. Instead of picking a specific date, click the calendar icon and select “flexible dates.” The app shows prices for the entire month. You’ll immediately see which days are cheapest. Then use the price tracking feature. Set it once, and Google emails you when prices drop.
Limitations
You can’t actually book through Google Flights. You’re always redirected elsewhere. This extra step isn’t major, but it means one more click before you complete your purchase.
Skyscanner
What It Does
Skyscanner compares flights across nearly every airline and booking site globally. The app works in over 70 countries and searches in multiple languages.
Why It Stands Out
Skyscanner excels at finding unusual routes and deals that other apps miss. Its algorithm searches obscure booking combinations that most people overlook.
The app offers:
- Whole month price calendar showing all flight options
- Price alert notifications
- “Everywhere” destination search for discovering budget flights
- Multi-city trip planning
- Hotel and car rental booking alongside flights
Best For
International travelers and people booking complex trips. If you’re flying from a smaller city or need to visit multiple destinations, Skyscanner often finds better deals.
How to Use It Effectively
The “Everywhere” feature is Skyscanner’s secret weapon. Type in your departure city, select “Everywhere” as the destination, and the app shows cheapest flights to every possible destination that month. This helps you choose where to travel based on price.
Limitations
The interface can feel cluttered compared to competitors. It offers so many features that new users sometimes feel overwhelmed.
Kayak
What It Does
Kayak combines flight search with price predictions. It shows you current prices and predicts whether fares will rise or fall in the next week.
Why It Stands Out
The price prediction tool is genuinely useful. Kayak uses historical data and current trends to forecast price movements. The tool tells you whether to book now or wait. This saves thousands of dollars annually if you trust the predictions.
Additional features:
- Flexible date search
- Price tracking across all major airlines
- Trip insurance recommendations
- Hotel and car booking integration
- Mobile app with offline access to booking confirmations
Best For
People who struggle with the “should I book now or wait?” question. If you want data-driven guidance on timing, Kayak helps tremendously.
How to Use It Effectively
Enter your flight details and check the price prediction. If it shows a green down arrow, prices are likely falling, so wait a few days. A red up arrow means prices are rising, so book immediately. This single feature has saved savvy travelers significant money.
Limitations
Price predictions aren’t perfect. They’re right about 70-80 percent of the time, but rare market shifts can still surprise you.
Expedia
What It Does
Expedia is a full travel platform. You book flights, hotels, car rentals, and activities all in one place.
Why It Stands Out
Expedia bundles flights with hotels and cars, often offering package discounts that beat booking separately. For example, booking a flight and hotel together sometimes saves 15-25 percent compared to separate bookings.
Key features:
- Rewards program that earns points on every booking
- Loyalty perks like free hotel upgrades
- Package deals combining multiple services
- One-stop booking for entire trips
- Flexible cancellation on package deals
Best For
People booking complete vacations. If you need flights, hotels, and rentals, packages often cost less than booking each separately.
How to Use It Effectively
Don’t just search for flights alone. Enter your trip details including accommodation needs. Then switch to the “packages” tab. Compare the bundled price with individual bookings. Usually, packages offer better value.
Limitations
Sometimes the package pricing includes hidden markups. Always check that the total package price actually beats booking separately before committing.
Booking.com
What It Does
Booking.com started with hotels but expanded to flights. It’s primarily known for accommodation but offers competitive flight prices.
Why It Stands Out
Booking.com combines flights with hotel booking in one ecosystem. If you’re already planning your accommodation, their flight prices are competitive.
The platform includes:
- Extensive hotel inventory alongside flights
- Rewards program for loyalty
- Free cancellation on most hotel bookings
- Package deals similar to Expedia
- Transparent pricing without surprise fees
Best For
Travelers who want to coordinate all travel arrangements in one app. If you’re booking hotels first, checking their flight prices makes sense.
Limitations
The flight selection sometimes lags behind dedicated flight apps. For pure flight search, Skyscanner or Google Flights usually offer more options.
Momondo
What It Does
Momondo is a flight metasearch engine owned by the same company as Kayak. It searches across airlines and booking sites to find the cheapest flights.
Why It Stands Out
Momondo finds flights that other search engines miss. Its algorithm searches booking sites differently than competitors, uncovering deal combinations other apps skip.
Useful features:
- Unusual route discovery
- Price calendar for entire months
- Budget flight filters
- Airlines sorted by carbon emissions
- Week view comparing prices across seven days
Best For
Environmentally conscious travelers and people seeking obscure deals. If you want to book the flight with the lowest carbon footprint, Momondo provides this option.
How to Use It Effectively
Use the carbon emissions filter to book eco-friendly flights. If you care about environmental impact, this feature sets Momondo apart from all competitors.
Limitations
The interface isn’t as polished as Google Flights. It works fine but feels slightly outdated compared to newer competitors.
Cleartrip
What It Does
Cleartrip is a travel app focused on Asia-Pacific markets. It specializes in flights, hotels, and bus tickets across this region.
Why It Stands Out
If you’re booking flights within Asia or from Asia internationally, Cleartrip often shows flights other apps miss. It has partnerships with regional airlines that global apps don’t feature prominently.
Key features:
- Bus and train booking alongside flights
- Regional airline partnerships
- Quick booking interface optimized for mobile
- Reward points program
- Regional payment options and currencies
Best For
Travelers in Asia booking regional flights. If you’re traveling through Southeast Asia or South Asia, Cleartrip usually beats global competitors.
Limitations
Outside Asia, this app offers little advantage. It’s designed specifically for that region.
Agoda
What It Does
Like Booking.com, Agoda primarily handles hotels but expanded to flights. It’s particularly strong in Asian markets.
Why It Stands Out
Agoda offers aggressive discounts in Asia, particularly Southeast Asia. Loyalty rewards are generous, and the app frequently offers flash sales on flights.
Features include:
- Strong Asian hotel inventory
- Competitive flight prices in that region
- Loyalty rewards that accumulate quickly
- Frequent flash sales
- Mobile-first design
Best For
Budget travelers in Asia. If you’re visiting Southeast Asia, Agoda’s discounts are often the cheapest available.
Limitations
The app focuses on Asia. For other regions, you’ll find better options elsewhere.

Step-by-Step Guide to Booking Flights with Apps
Step 1: Decide on Your Flexibility
Before opening any app, answer these questions:
- Are your dates fixed or flexible?
- Must you fly on specific days?
- Can you change departure times if cheaper options exist?
Flexible dates save substantial money. If you can shift travel by even a few days, do it. Check multiple dates in your app’s price calendar.
Step 2: Start with Google Flights
Open Google Flights first. It doesn’t bind you to anything, just shows available options. Search your route using flexible dates. Check the price calendar.
Note the lowest prices and the dates they occur. This establishes your baseline.
Step 3: Cross-Check with Skyscanner
Run the same search on Skyscanner. Compare prices. Sometimes Skyscanner finds cheaper flights through unusual routing. If prices differ significantly, investigate why.
Step 4: Use Price Prediction Tools
If prices vary between apps, use Kayak’s price prediction. Should you book now or wait?
Look for patterns:
- Green arrows mean book later
- Red arrows mean book now
- Flat arrows mean prices are stable
Trust the prediction but verify it makes sense for your situation.
Step 5: Check Booking Details
Before committing, verify:
- Baggage allowance
- Seat selection costs
- Cancellation policy
- Layover times and locations
- Total journey duration
One app showing a cheaper price might include fees the other doesn’t. Calculate the true total cost.
Step 6: Book on the Official Website
Whenever possible, book directly through the airline’s website. Direct bookings sometimes offer:
- Better customer service
- Easier modifications
- Exclusive airline rewards
- Lower prices (occasionally)
If you found the flight through a third-party app, click to the airline’s site and complete the booking there.
Step 7: Save Your Confirmation
Screenshot or download your booking confirmation. Save it in your email and phone. If your app loses the confirmation, you have backup copies.
Set a phone reminder for check-in time (24 hours before departure for most airlines).
Common Mistakes When Booking Flights Through Apps
Mistake 1: Ignoring the Total Price
Apps sometimes show base fares but hide taxes and fees. Always look at the final total before booking.
Example: App A shows $150. Final price is $185 after taxes.
App B shows $160. Final price is $162 after taxes.
App B is actually cheaper, but you’d miss this comparing base fares.
Mistake 2: Forgetting Baggage Costs
Budget airlines charge for carry-on and checked bags. A cheap flight becomes expensive when you add baggage.
Compare the all-in price:
- Flight cost
- Baggage fees
- Seat selection charges
- Any other add-ons you need
Mistake 3: Not Reading Cancellation Policies
Some apps show “non-refundable” tickets in small text. Check the cancellation policy before booking.
Budget airlines often sell non-refundable tickets at lower prices. Premium airlines usually allow changes. Choose based on your situation.
Mistake 4: Ignoring Layover Times
A two-hour layover sounds fine until your first flight arrives late. International connections need 3+ hours. Domestic connections need 2 hours minimum.
Check layover duration in the app’s detailed flight view.
Mistake 5: Not Comparing Alternative Airports
Flying into the alternative airport sometimes costs significantly less. Check nearby options.
Example: Flying to New York could mean:
- LaGuardia (closer, more expensive)
- Newark (further, cheaper)
- JFK (medium distance, medium price)
Most apps let you search multiple airports. Try alternative options.
Mistake 6: Missing Loyalty Program Opportunities
If you fly regularly with one airline, book directly with them. Frequent flyer miles accumulate faster.
Apps sometimes show prices that exclude loyalty program benefits. Direct booking often earns more miles.
Mistake 7: Not Using Incognito Mode
Websites and apps sometimes raise prices based on your browsing history. Open incognito mode when comparing prices across multiple searches.
This prevents cookie tracking that inflates prices.
Money-Saving Tips When Using Flight Booking Apps
Search in Incognito Mode
Open your browser’s incognito or private window before searching. This prevents tracking cookies from influencing pricing.
Set Price Alerts Multiple Months Early
Most apps let you set alerts 3-6 months before travel. Price alerts work best when set early. Monitor price trends for several months before booking.
Fly on Unpopular Days
Tuesday and Wednesday flights cost less than Friday and Sunday flights. Check the price calendar. Most people travel on weekends, driving up prices.
Search Nearby Airports
If you live near multiple airports, search all of them. The price difference is often substantial.
Example: Dallas residents can fly from Dallas Love Field, Dallas Fort Worth International, or sometimes even Austin. Prices vary by hundreds of dollars.
Book Flights Separately from Hotels
While package deals seem attractive, booking separately often costs less. Search packages but always compare with individual bookings.
Use Airline Apps Directly
Some airlines offer exclusive discounts through their apps. Southwest, JetBlue, and others frequently feature deals unavailable elsewhere.
Be Flexible on Dates and Times
Red-eye flights cost less. Early morning flights are cheaper than afternoon flights. Tuesday midday flights are cheapest overall.
Being flexible multiplies your savings potential.
Clear Your Cookies Before Booking
Use incognito mode when you’re ready to book. This prevents price inflation from previous searches.
Book Round-Trips Instead of One-Ways
Surprisingly, round-trip bookings often cost less than separate one-way tickets.
Consider Budget Airlines for Specific Routes
Budget airlines are cheaper on certain routes but expensive on others. Don’t assume they’re always cheaper. Compare with full-service carriers.
App-Specific Tips and Strategies
Google Flights Pro Tips
Use the “Track prices” feature on specific flights. Google notifies you via email when prices change.
Set your notification preferences to alert you only for price decreases.
The “Show outbound flights” and “Show return flights” filters let you compare outbound and return flights separately, maximizing savings.
Skyscanner Power Moves
The “Entire month” view is essential. Most people miss this. It reveals the cheapest date in your travel month at a glance.
Use the “Everywhere” destination search to discover cheap flights you hadn’t considered.
Filter by stops. Sometimes a one-stop flight costs less than direct flights. Budget flights often include stops; consider whether the savings justify the time.
Kayak Advanced Strategies
Enable price drop notifications. Kayak alerts you immediately when prices fall.
Check the price prediction multiple times. Markets shift. A prediction can change from “book now” to “wait” within hours.
Use the “Price Map” to see flight prices to nearby destinations simultaneously.
Expedia Package Booking Strategy
Always calculate package pricing:
- Flight cost
- Hotel cost per night
- Number of nights
- Compare against individual bookings
Sometimes packages cost more despite appearing cheaper. The math reveals the truth.
Booking.com Secrets
When booking hotels and flights together, check if booking them separately costs less. Booking.com’s package discounts aren’t always genuine savings.
Use Booking.com’s free cancellation on hotels. You can book a hotel now and cancel later without penalty if plans change.
Addressing Regional Variations
Flight booking apps perform differently across regions. Where you live matters.
In North America
Google Flights and Kayak dominate. Both are optimized for US and Canadian routes. Expedia and Booking.com offer competitive pricing.
Southwest Airlines doesn’t appear on most booking apps. Search Southwest directly for their flights.
In Europe
Skyscanner and Google Flights are strongest. Budget airlines (Ryanair, EasyJet, Wizz Air) are popular. Direct airline booking often beats apps.
Some European airlines don’t appear on all metasearch engines. Verify that your preferred airline appears in search results.
In Asia
Cleartrip and Agoda excel here. Regional airlines don’t appear on all global apps. Local apps sometimes show better pricing.
Consider booking directly with regional airlines for routes within Asia.
In Australia and Oceania
Google Flights and Skyscanner work well. Check local airlines like Qantas and Air New Zealand directly. Regional pricing
