What time does Greensboro airport open?

You are usually good to show an hour before your flight. I like 1.5 so I can enjoy a cup of coffee!

They are NOT open 24/7. The doors may be open, but no one available. No shops, no restaurants, no check in people. I've been plenty of times at 4:30 and had to wait for check in or going through security til at least 5am.

We are open 24 hours a day. Are you asking about screening or a particular airline?

Please where is the staging area for uber and lyft drivers?

24/7. like all international airports.
