Preboard Plan
Work backward from your flight to the time you should be at the airport. It's a transparent calculator — you can see every step — not an AI prediction.
Import from a confirmation email or calendar file
Paste the text of your confirmation (leave out names and confirmation codes), or choose an .ics file. We read it once to find flights and keep nothing.
