Mmm, interesting. So perhaps airline service levels have hit bottom and will have to go up if occasional repeat passengers are willing to pay for better food and entertainment systems?

OP, I think what folks are trying to say is that you may find service breaks on most airlines and that switching carriers due to one poor experience has led them on a merry-go-round of carrier switching.

Then again, I have learned from my wife and sister that such emotionally based decision-making is common and there's nothing intrinsically wrong with it, it's just suboptimal. And there's nothing wrong with living a suboptimal life. mherdeg knows what I'm talking about.

Let us know if UA customer service gets back to you after your complaint. Mistakes happen at every company. It's what they do after mistakes happen that is the measure of the company.
