Spot a wrong number, have a partnership idea, or a question about the site? We would like to hear it.

First Class Passport is built to be the fast, accurate answer to "will my bag fit," and that only works if the numbers are right and the site actually helps. If something is off, or you just want to reach us, email [email protected] and we will get back to you.

What to write in about

Corrections are the big one: if an airline has changed its carry-on size or bag fee since we last checked, or you found a number that does not match the airline's own page, tell us and we will re-verify it. We also welcome partnership and press inquiries.
