The one terrible experience I had with United is when I was flying from Japan to SFO connecting at LA. We arrived at LA and didn't see our connecting flight on the flight status screen and went to customer service. The lady said "well it was cancelled and they should have told you in Japan. We can't help you now." Both flights were WITH united and when I asked for another flight she said "I'll send you tomorrow. OK?!" Well it wasn't nearly as bad as some of the others' have experienced and didn't cause me to boycott them but these recent allegations that have surfaced seem pretty serious.
