Pros: We were connecting and the connecting flight was late and the CSR held the plane just for us.
Cons: Once on board the crew was horrible. Because of the problem, some other groups of people decided to take our seats to spread out. So I just took the seats immediately available to us that were open. The flight attendant decided to check our boarding pass to see if we were in the right seat, and of course we were not (because the other people decided to take our seats as we were the last to board). I figured this was just fine. We even paid extra for the assigned seats but for the sake of getting the flight going due to our tight connection, we took the nearest available seats. Unfortunately, a group of 6 people had to take 5 minutes to rearrange the seats because the flight attendant "insisted" we take the seats on our boarding pass. It would have been much easier if the crew would have just let us take the seats that were available instead of trying to rearrange the other group.
