You guys crack me up!
Yes, SW is not only safe, and cheap but fun. They have a "relaxed" attitude here are some reported examples:
Once on a Southwest flight, the pilot said, "We've reached our cruising altitude now, and I'm turning off the seat belt sign. I'm switching to autopilot, too, so I can come back there and visit with all of you for the rest of the flight."
From a Southwest Airlines employee.... "Welcome aboard Southwest Flight XXX to YYY. To operate your seatbelt, insert the metal tab into the buckle, and pull tight. It works just like every other seatbelt, and if you don't know how to operate one, you probably shouldn't be out in public unsupervised. In the event of a sudden loss of cabin pressure, oxygen masks will descend from the ceiling. Stop screaming, grab the mask,and pull it over your face. If you have a small child traveling with you, secure your mask before assisting with theirs. If you are traveling with two small children, decide now which one you love more.
Gotta love that!
