How can I import flights to App in the Air?

You have these options:

1. Connect any email to parse inbox itineraries from airlines.
2. Connect your TripIt account to synchronize your flight's history.
3. Forward your email confirmations to just@add.flights to add them to your flight feed.
4. Send CSV files (my.flightradar24 (formerly flightDiary), Open flight, custom CSV that can found in attachments) to just@add.flights
5. Connect your Loyalty program to import flights and check your miles/points via App in the Air. You can also find the TripCase as an option in the program list (only future flights are imported).
6. Connect your Calendar to import flights and synchronize your flight history.
