Super easy and friendly app to track your flights, family, and friends. I use it when going to pick someone up at the airport too. Super useful, with lots of airport info.
This is the best traveling and tracking app I have ever used. So easy and convenient. Everything is synchronized in one place.
Excellent app for keeping track of my flights during an arctic freeze snowstorm. It kept me updated on delays and cancellations and helped keep my stress low.
Easy to add flights and track real-time delays before the airlines report them at the airport. So far it’s been great!
I find that sometimes airlines don’t notify you about flight changes, but byAir is trustworthy in sending me flight information.
This app transformed the way I travel. It gives me real-time flight updates, helps me navigate airports, and sends timely gate-change alerts.
Keep Cathay Pacific for the booking. Add byAir for every connection around it.
