I recently went on vacation to Vieques, which is one of the smaller islands in Puerto Rico, South-East of the main island. Two options to get there from San Juan: drive across the main island to catch a ferry (and waste a whole day), or brace yourself and fly Vieques Airlink. We opted for the second option, and it was quite epic...
First the airport: the person at the check-in counter was a fifteen year old kid wearing shorts and flip-flops, he never checked our IDs but instead asked us to write down our name and weight (!) on a sheet of scrap paper. 45 minutes later, we're boarding a tiny propeller airplane with 8 seats... the pilot is talking on his cell phone while taking off... seriously!
I guess I'm making it sound worse than it really was... we landed safe and sound in Vieques after 20 minutes over the ocean, and I actually enjoyed it (though some of my travel companion who aren't so much into flying almost had heart attacks!). And as I hear from locals, it is much more reliable than the ferry, which runs on a rather arbitrary schedule. Not for the faint of heart, but it was actually quite fun. read more
