byAir vs. Singapore Airlines

Keep Singapore Airlines for official service. Add byAir for every carrier in the trip.

The SingaporeAir app handles Singapore Airlines and selected partner bookings, check-in, boarding passes, seats, meals, entertainment, KrisFlyer, official updates, and eligible baggage tracking from Changi.

byAir adds one timeline across carriers, independent provider context, cross-airline history and statistics, and early delay signals on eligible flights.

One official app. One independent trip view.

Singapore Airlines controls its booking, services, and loyalty benefits. byAir adds a carrier-neutral view across partners, separate tickets, and the rest of the journey.

What byAir users say

Jose M Iturralde

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.

Hardeep Singh

This is the best traveling and tracking app I have ever used. So easy and convenient. Everything is synchronized in one place.

Janet Osborne (JaLyn)

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.

Eli Lopez

Easy to add flights and track real-time delays before the airlines report them at the airport. So far it’s been great!

James Muri

I find that sometimes airlines don’t notify you about flight changes, but byAir is trustworthy in sending me flight information.

Drew Srk

This app transformed the way I travel. It gives me real-time flight updates, helps me navigate airports, and sends timely gate-change alerts.
