I've never flown seaborne. I love the Cape Air flight. Yes its small, but the views are worth the price of admission alone.

We also like the commuter book since we haven't had any trouble using all 10 one-way coupons in a year. Works great when we have others with us as we use them very quickly that way and it locks in that leg of the trip. So it's just getting the flights to San Juan as cheap as we can.
