A flight has a departure time. Getting yourself to the airport needs one, too.
I built Departure Time to answer a practical question: When should I leave?
Choose your airport and flight time, then account for the parts of the trip that are easy to overlook: the drive, parking or returning a rental car, checking in, dropping a bag, security, and the walk to your gate.
A plan you can adjust
Get a suggested leave-by time with an itemized breakdown.
Set your own security, walking, and extra buffer time.
Save your timing preferences in your browser for the next trip.
Open a prefilled Google Calendar event for your airport departure.
The timing is an estimate, so give yourself the margin your trip needs. The goal is to make the calculation easier to understand and change.
It’s free to use in your browser. If it takes a little stress out of a travel day, a coffee here helps support the next useful little tool.
Originally released June 20, 2025, as Airport Departure Planner. This launch note was added to the MNSinLA archive in September 2026; the link above goes to the current version.
