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).
