Your Airline App
Before you board the plane, make sure you have the app for your airline downloaded on your phone or tablet.
You can use this to track some of your progress, have other trip information on hand and it's going to help you out if you need to get around a delay.
In the air, you can often use these apps to watch movies and tv shows from the airline without paying for WiFi or download anything before you take off.
We never fly without the Delta app. The United app is a must have if you want to watch movies and TV shows while you are on a United plane without screens.
Search your app store for the app for your airline.
