If you’ve already checked in online and you’re traveling only with carry‑on baggage, you can arrive at the airport about 1.5 hours before departure. Learn more about online check-in. If you haven’t checked in, we recommend arriving about 2.5 hours before departure. That way you won’t be in a rush to find your flight on the board, figure out which desk to go to and get checked in. If you’ve checked in online but you’re flying with baggage, the same advice applies – arrive 2.5 hours before departure.
