How long before your flight do you have to be at the airport? 2 hours,it gives you enough time to park,cheak-in maybe do some shopping and then go through security. Make sure you have enought time to get to your gate and board the aeroplâ¦ane-about 20-30 mins in case you get lost.
Re: How many hrs. before flight should I arrive at Airport. Jul 15, 2012, 9:21 AM. Security to the US takes longer than to other countries so you'll need to be there 2 hours before the flight. If you are traveling business or first and can go through priority lanes, then you could cut it down to 90 minutes.
