My 13 year old daughter and I flew Southwest to see my sister in March. It was her first time flying and loved it. The check-in process is very easy on their app. The quicker you check in, the better your seat choice. We just went to the airport and printed our tickets, then waited for them to announce boarding. They board you in groups, then you pick your own seats. The flights attendants were nice, and some were very funny with their announcements and safety procedures. We got the standard snack and drink on all of our flights. The best part of Southwest is that bags are free!
