I agree with Gary 100% re flights straight from PR to Europe, of which there are very few. Flying west 6 to 9 hours from Europe to the US East Coast in order to turn around and fly 4 hours southeast to PR is annoying. And the Homeland Security lackeys have a wonderful knack for being rude and condescending even at the overseas pre-US flight screening stations (at Dublin, for instance).Â
A warning to those using Jet Blue to connect to a Europe-bound flight through Boston Logan: You'll have to exit Terminal 3 completely, enter another terminal (often if not always Terminal 4), re-check in, and go through the security theatre all over again in order to get to your gate. Idiotic!
