15 year old flying Southwest?

I am 13 & always fly southwest. You're not an unacompanied minor anymore, you are considered an "adult" at 12. You would not have to bring any birth certificates, and yes, you can take connecting flights. Being an "adult" now, means you can basically do anything your parents would do as well. You can choose your own seats instead of being put in the front too. Southwest is a great airline! While they don't have tv's or anything their crews are funny. Go on youtube & look up "Rapping Flight Attendant on Southwest". Hope this somewhat helped & have fun on your flight! Be safe :)
