Thanks, Eric. Actually what I've posted here is much of the letter I sent to United on my return. I addressed it to Diane Soucy Bergin, Director of UA Customer Relations; it was answered by one of her staff. On Saturday, I received the $50 voucher with a cover letter that included the sentence "Regretfully, during flight our options are limited, especially when the flight is full." I then followed up with a phone call to UA Customer Service today. That rep just kept saying "It is not United's responsibility. We even print that we are not responsible for customer behavior on the cover of Hemisphere's magazine."
