The JetBlue app is the official place to book or change a JetBlue trip, check in, open a boarding pass, choose seats and extras, track eligible bags, and manage TrueBlue.
byAir complements it with one timeline across airlines, independent flight-data context, personal travel statistics, and early delay signals on eligible flights.
JetBlue controls travel tied to a JetBlue booking. byAir adds a carrier-neutral view across connections, separate bookings, and the rest of the journey.

JetBlue remains the official source of truth for a JetBlue-issued booking.

byAir Predict monitors eligible flights and separates its predicted departure time and likely reason from the airline’s official status.
Import from Gmail, Outlook, a calendar, a forwarded email, or Quick Scan—then follow the whole trip in one place.
byAir Predict metrics cover eligible, verified delays of 10 minutes or more. Availability and lead time vary by route and data coverage; these figures are global, not airline-specific.
Book fares, manage a JetBlue itinerary, check in, open a boarding pass, select seats and extras, see official flight and gate updates, track eligible checked bags, use TrueBlue or Travel Bank, and contact JetBlue from the airline’s own app.
Publicly listed app capabilities reviewed in July 2026. Airline functions remain subject to the carrier’s current app, route, airport, device, and itinerary eligibility.
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 JetBlue for the booking. Add byAir for the journey around it.
