Do I Really Need to Arrive Two Hours Early for an International Flight?
Trip Doctor’s Answer
Here’s the official rule: you and your luggage must be checked in at least an hour before departure, and you’ve got to be at the gate 30 to 45 minutes early. (There are a handful of exceptions; check with your carrier.) If you check in online and only have a carry-on, you’re free to play it closer—just don’t forget about the security lines.
