My .02: More flights into BC, but economics drive this. (Selfishly I want a flight direct from Phoenix to BC.)
I really ejoyed the Tropic flight to and from BC to SP. The view was great and it only added about 1 hour to the day, but well worth it. I stayed at Ruby's and didn't hear 1 airplane the entire 10 days form the hotel. I don't think that would be the case with 727's, etc. flying direct to SP.
