A group of 12 and I was so nervous to do the flight check in lottery system. I got to the airport and they do all our boarding passes, and free luggage check in. We were in zone B and easily all 12 got their seats, and a couple of us switched so that families could sit together and vice versa. The check in agents and the gate agents were professional, polite and helpful. The flight attendants were very nice, and helpful and gave all a good laugh. The pilot was amusing, and it was a good landing. The whole crew made the experience so wonderful, and now it will always be Southwest.
