Living in Atlanta we deal with the same thing with Delta.
Any day of the week, anytime of the year you can fly from many places in the U.S. on a connecting flight through Atlanta and pay less than we pay living right here.
...AND we will not go into how much cheaper a flight from the NY metro or Boston area is and is a good deal further away from Aruba than Atlanta. But right now there is no competition non-stop out of Atlanta. Just hoping when Air Tran starts it is year 'round.
Just booked Jet blue from Portland Maine to Aruba... via JFK , Mid week travel in April $420 pp, including all taxes round trip..... not bad..... I could be packed and out the door in 5 minutes so it's going to be a long 6 months!
