Check In While You Sleep
If your airline's check-in window opens while you are asleep, set up the task beforehand. For example: “Check me in for tomorrow's flight when online check-in opens and text me with the result.” Airtap can run the supported workflow at the scheduled time without requiring you to set an alarm just to open the airline app.

When the check-in attempt finishes, Airtap messages you with the result or tells you if the airline requires something from you.
