we always fly back on a sunday. I would definitely say no less than 2 hours at the airport but since you're unfamiliar with the layout and routine, I'd be safe and be there a minimum of 2.5 hours. They have bars there so even if you get through early, you can have a bite to eat and a drink. As Andrea said, there are two security points you have to go through. Sometimes you zip through and sometimes you don't. Airports are unpredictable in Aruba and the USA. The good news is that when you get back to the states, you just get your luggage and leave, no customs. So look at it that way. It takes longer in Aruba but shorter when you land. It really is six of one and half dozen of the other. sometimes I think people forget that when they say it takes so long to go through the airport in aruba but if you didn't have the customs there, you'd have to do it in the states. for me, I'd rather get it over with in aruba. once I land, I just want to get home.
