I'm sorry to hear of your horrific experience with United. I am a disabled person and had the misfortune to travel with them from SF to Sydney some time ago. Everything went wrong from the time I checked in at SF until to my arrival at Sydney. To add insult to injury, the flight attendant refused to carry my hand baggage to the wheel chair as it was an OH&S issue for her to carry my 5 kg hand baggage!!! I complained and got a $200 voucher to be used on my next trip with them. Do they seriously think that I will ever travel with them? I never will and I have made sure none of my friends or family will every use this airline.
