If my flight is at 6:00 am and I just have a carry on, how early should I be there? Also, if someone is driving me are they able to drop me at the terminal? Thanks!

Yes, drop off is right in front. I would be there between 4:45- 5, MesaGateway is very easy and quick on getting you through.

The airlines suggest you arrive up to 2 hours before your flight. If you are not parking, already have a boarding pass and only have a carry on, you should be ok arriving in the 1 hour to hour and a half range depending on your familiarity of flying. There is a passenger unloading zoning right in front of the door for the security checkpoint.
