Going to Aruba Mar 6-17. I booked on Travelocity.com. Detroit to Aruba aboard Delta. Not a direct flight but cheaper than our other family members got thru a travel agent! I'd start at Travelocity.com
The best deals are the packages including charter airfare. Otherwise, I have had the best luck with priceline or expedia. We had to fly Detroit-Chicago-Miami to Aruba this year to make the fare tolerable. That was a bit much for us, especially coming home. The carrier was American.
