Cons: They cancelled our return flight for no reason. Two hours in, the front desk had only managed to accommodate 2 families. We were in San Juan at peak season, so all hotels were full. We were eventually put on a connection to Miami, had to wait a few hours in that airport for our next flight, a multi- stop Southwest flight to Richmond, Atlanta and finally Baltimore. it took us 24 h to get home, instead of a direct flight of 3h. Just because the comoany decided we were not worth serving

Cons: I don’t know what they did with my fly, but I did my check in 24 hours before and everything was ok, but they when I get at there ready to fly they told me the fly was for the next day.

Cons: The flight attendants were extremely loud and inconsiderate on this flight. With it being a later evening flight usually flight attendants are quieter to allow people to sleep. On this flight however, the flight attendants were extremely loud the whole time, laughing and just not being considerate of the rest of us that wanted to sleep. I have never experienced this on a flight before. They were so loud we heard their entire conversation from what they did on their free time in the summer, to what they think about game of thrones & talking about their fitness. They were loud the entire flight.
