??? I just checked Delta from YYZ to STT and SJU. DL 2551 leaves YYZ at 6:15 am to ATL. DL 517 goes to STT, arriving at 1:38 pm. DL 559 goes to SJU, arriving at 1:30 pm. Cost to STT looks like its about $250 less than SJU. So, isn't it just as easy, and cheaper, to get to STT? And, you get a free rum shot at STT!

(I must admit I am prejudiced against SJU. Back when AA owned the Caribbean, we made multiple trips through SJU to Canouan, St Lucia and Beef Island. Perhaps the food has improved, but if I never have another chicken quesadilla at SJU, I won't miss it all!)
