JetBlue booked us from Fort Lauderdale to Culebra, P.R., using Seaborne Airlines to get us from San Juan International to Culebra on an island-hopper, which seats about 10 people. But Seaborne Air doesn't actually even fly to Culebra, instead THEY put us on Vieques Airlink, which was ok, except.......Even though i was only traveling with carry-on bags, they weighed my 21 inch suitcase and my tote bag and charged me $25 extra for "weight overage." I had to hand over my credit card, but they couldn't even give me a receipt, because they don't have any means to print them. This was really lame. Their terminal was dark dirty and dingy too.
