I have never been based in SJU, but have spent a lot of time there visiting friends who were based there. Operations run as slow as molasses, youll be hot all the time, and the overnights are short. On the bright side, if you like to drink, gamble, or chase women you will have a blast Also great surfing, beaches, snorkeling, sailing. The flying is some of the most beautiful in the system and youll be a better pilot for it (NDB holds, crazy ass visual approaches) It is what you make of it, so start learning spanish!
