tlb,
you mentioned previously travel to pto rico - i got the feeling you were referring to making the trips for things you need to accomplish on u.s. soil.
with jetblue or spirit a trip to NYC or Ft Lauderdale might be cheaper than a trip to pto rico. at times those flights go for under $10 each way + taxes (with taxes being $150-$180+/-)
