I love Southwest Airlines for not charging for luggage. That's a pretty good saves right there. Short flight from Las Vegas to San Francisco, which make me happy.
The staff were usually friendly. The offer nonalcoholics drinks and snacks for free. =)
It's first come first serve for the seats. Hopefully, you will be like and get an "A something" so you can seat where ever you like.
Great prices always to Las Vegas. Wifi is extra charge.
