Yes. The core app is free on both iOS and Android, and push notifications are included at no cost — which is unusual among flight trackers. A Pro subscription unlocks additional features, but most travelers won't need it.

Never Miss a Flight Again With ByAir—Or Get There Too Early

Q: How does ByAir compare to Flighty?

Both focus on your specific trip rather than all air traffic, but Flighty uses live ATC data for earlier delay alerts and has a richer flight history feature. ByAir's big advantage is cross-platform availability — it's the go-to for Android users since Flighty remains iPhone only.

Q: Can ByAir track international flights?

Yes. ByAir handles international routes well and includes destination weather as part of its free flight overview, which is a useful perk for international travelers.

When App in the Air shut down, Android users who relied on it for trip-focused flight tracking were left looking for a replacement. ByAir stepped in as a solid, no-fuss flight tracker. It's a cross-platform app that both iPhone and Android users can enjoy, and delivers free push notifications without having to pay for a premium.

I tested ByAir alongside five other apps for WhistleOut's roundup of the best flight tracking apps. Here's what it does well, what it's missing, and who it's the right pick for.

Free for iOS and Android.
Pro subscription available.

What is ByAir?

ByAir is a cross-platform flight tracker that focuses on your specific trip rather than every flying aircraft around the world. Add in a valid flight number and the app builds a dashboard around your journey, which includes delay probability, destination weather, airport departures and arrivals, and even directions to your terminal.

ByAir is the app for travelers who want to understand what's happening with their own flight, not an aerial view of every plane in the sky (like Flightradar24).

ByAir is currently the biggest cross-platform competitor to Flighty. Since Flighty is only available for iPhone, ByAir is currently the strongest trip-tracking option for Android users.

MVNOs are smaller mobile carriers that use the same AT&T towers for a fraction of the price. If you're on AT&T, compare the top MVNO plans below before your trip and see what you could save.

All your flight info on one screen

Adding your flight to ByAir only takes a few seconds, and it pulls together more information than you'd expect from a free app. You can look at your flight route, aircraft type, weather conditions upon arrival, departure and arrival gates, and even the probability your flight may be delayed.

Honestly, delay prediction is the best ByAir feature. It gives you a probability rating for how likely your flight is to be delayed based on current patterns and general airport traffic. That way, you don't need to rush to the airport in order to arrive obscenely early (I would know).

On top of that, you get the current weather at your destination, which is a feature other flight trackers charge for. Plus, you can see all departures and arrivals at your airport, and directions to help you get there. It's a detailed trip view rather than a raw flight status screen.

Not sure how to update your apps?

Keeping your apps up to date ensures you're always getting the latest features, bug fixes, and security improvements. Learn how to update the apps on your iPhone and your Android. It takes less time than you think.

Travel tips that actually help you

At the bottom of your flight information, ByAir includes a bunch of customized travel tips—which caught me off guard, but in a good way.

ByAir surfaces practical local knowledge for major airports. I found out that JetBlue has a rooftop terrace at JFK that's accessible once you're past security. That kind of tip doesn't show up in a standard flight status app, and it's exactly the kind of thing that makes a long layover more bearable.

Every detail imaginable, except this one

My only real gripe with ByAir is that it doesn't explain why a flight is delayed or canceled. I was checking the app on a day with active tornado warnings in the region and could see that multiple flights were affected, but the app offered no explanation. You get the flight status, but not the context—and context matters when you're deciding whether to head to the airport or stay put.

For a better picture as to why your flight is delayed, you need to cross-reference the airline's website. It's a gap worth knowing about, but it's not a dealbreaker for most travelers.

Push notifications are free with ByAir, which is a plus that other flight trackers lack. All in all, ByAir is a solid flight tracker for your next overseas trip.

What does Reddit think about ByAir?

After App in the Air shut down, users looking for alternatives quickly landed on ByAir. u/BrokeDXBStudent on r/byair said, "ByAir has been such a blessing this year, especially as an Android user. You have filled the App in the Air gap perfectly and added so much more functionality."
