Nothing is new here about my bad experience. But hopefully I can shed some light into their evil world. And then the travelers can choose wisely.\n\nUS Worst has retained its title for me in 2011.\n\nTypical story. Mechanical failure. Flight was delayed in Palm Springs. I missed the connection in Phoenix. I was rescheduled for later flight. A delay of 4 hours.\n\nI always avoid US Worst but sometimes it's just impossible. It helps when US Worst is part of Star Alliance (Wrong... more later). I was a United Premier member. I thought I still can get my benefit on US Worst. That's a wrong assumption.\n\nI have experienced nightmares on more than 50% of US Worst flights. More so lately... 100% in past 2 years (2 flights). Luckily I've shifted all possible flights to other not so worst airlines.\n\nTo make a long tedious nightmare educational:\n1) US Worst does not recognize the full status of United Premier. Not like United and Continental.\n\n2) It's business as usual for US Worst. The costumer service rep expressed indifference. It reminds me of rental clerks in Las Vegas and FlorIda (\""you don't like it? Too bad! Move aside, there's a long line waiting for our premiere service\"") There is no apology. The mechanic failure and that delayed flight did not qualify for any compensation.\n\nSo travelers, kowtow to the Almighty US Worst whom provides world class service to everyone. I wonder what service you will get in economy class.
