Just got back last night. Had a 3pm flight with Delta yesterday (Tuesday). Got to the Aruba airport at 12:20pm and was at my gate by 1:10pm (helped a little though that I was in the First Class lane at the ticket counter so I bypassed the longer line.) Smooth sailing all the way home. Probably also helped that I flew home on a Tuesday, too. There were 4 U.S. Customs booths open.
