You think the front end charges are bad on Spirit? Just wait til you get on board. Advertising everywhere. All the overhead bins have advertising on them. The stewardesses make multiple passes down the aisle with a cart of crap to hawk, like credit card apps and stuff. Even the pilot gets on the intercom to convince you to participate in the wonderful deals offered on the plane. It will remind you of a timeshare offer weekend.

I used to fly Frontier, but the acquisition by Republic has killed them. Took a good basic middle of the road offering and crashed it to bottom basement. Sad really.

Generally fly United now as they go to the places I need to get to. Shows a little more on the ticket when searching fares, but much more reliable. And when things go wrong for them, they kick back rewards to apologize.
