Airline Apps: Which Features Are Actually Worth Using
Quick answer
Airline apps are most valuable on the day of travel: they hold your boarding pass, send gate and delay alerts, and let you rebook yourself during disruption without queuing. Download the app well before you fly, log in while you still have internet, and screenshot or save your boarding pass as a backup. Use the app alongside an independent flight tracker for the earliest warning of delays.

Why download the app at all
For a single flight, a website and an email confirmation can feel like enough. The app earns its place when something changes. Gate swaps, delays, cancellations and baggage updates tend to reach the app first, and in a disruption the app is often the fastest route to a new seat because thousands of other passengers are queuing at the desk.
The features that matter most
| Feature | Why it helps |
|---|---|
| Mobile boarding pass | No printing; works at bag drop, security and the gate where supported |
| Push notifications | Gate changes, delays and boarding calls on your lock screen |
| Self-service rebooking | Pick a new flight during disruption without waiting for an agent |
| Seat selection and changes | Adjust seats after booking, sometimes for free |
| Baggage tracking | See whether your bag was loaded |
| Digital documents | Receipts, itinerary and booking reference in one place |
Set it up before you leave home
- Install and sign in early. Airport wifi is slow and crowded, and some apps need a data connection to log in the first time.
- Add your booking reference. Enter it manually if it does not import automatically from your email.
- Turn on notifications. Allow alerts for flight status. Silent mode and focus modes can hide them, so test it.
- Add the boarding pass to your phone wallet if the airline offers it. This often works offline.
- Check passport and visa fields. Some airlines ask for travel documents during online check-in.
Using the app during a delay or cancellation
When something goes wrong, speed matters. Open the app first, because it may show alternative flights you can accept instantly. If the app only offers a rebooking you do not like, you can still go to the desk or call, but you will know your options before you speak to anyone.
Take a screenshot of any offer and of the original booking. If a dispute arises later, you have a time-stamped record. Keep in mind that accepting a voucher or a different routing in the app can affect your refund rights, so read the screen before you tap confirm.
Where apps fall short
Updates can lag
An airline app shows what the airline has loaded into its system. Departure boards and apps sometimes update a few minutes after the aircraft’s real situation changes. An independent tracker can show your plane’s inbound journey in real time. You can look up any flight on the ScanFlyGo flight tracker as a second source.
Too many apps
If you fly several airlines a year, a pile of separate apps gets messy. Keep the ones you use on active trips and remove the rest, or lean on your phone wallet for boarding passes.
Upsell prompts
Airline apps like to offer upgrades, lounge passes and extras. Treat these as optional and compare prices before buying.
Privacy, battery and safety tips
- Use a strong, unique password or a passkey for each airline account.
- Only download the app from your phone’s official store, and check that the publisher is the airline. Fake apps and fake airline sites exist, so see our guide to spotting fake airline websites.
- Carry a power bank. A dead phone with your only boarding pass is a common avoidable problem.
- Keep a paper or screenshot backup of the boarding pass and your booking reference.
- Be cautious on public wifi. Use mobile data for logins when you can.
Do you still need a metasearch?
Yes. Airline apps are for managing a booking with that airline. They are not designed to compare prices across the market. Use a metasearch to find the fare, then use the airline’s app to manage the trip.
Frequently asked questions
Do I need the airline app to board a flight?
Not always. Many airlines still accept a printed pass or one issued at the desk, though some low-cost carriers may charge a fee for airport check-in. Check your airline’s rules.
Is a screenshot of my boarding pass accepted?
Often it is not reliable, because scanners may need the live barcode. Treat a screenshot as a backup and add the pass to your phone wallet where possible.
Are airline apps better than the website?
For travel-day tasks, usually yes, thanks to notifications and quick rebooking. For comparing prices or complex changes, the website or a metasearch can be easier.
Can the app rebook me for free after a cancellation?
In many cases the airline will rebook you at no extra charge when it cancels your flight, but the options and rules vary. Read the offer before accepting.
The bottom line
A good airline app turns a stressful travel day into a few taps: boarding pass, alerts and rebooking all in one place. Set it up before you leave, keep a backup, and pair it with an independent tracker. Track your flight live, see popular routes, or search for your next fare on ScanFlyGo.
