I e-mailed united about my issue. Received a response directing me back to the UnitedCares site. They don't care that much about me because I only get a $200 E Certificate for my 15 hour mechanical delay.
I responded to the e-mail saying that I felt that $200 was rather small for such a delay, and received this response:
"Hi Patrick,I'm sorry the compensation offered on our
united.com/unitedcares didn't meet your expectations.
While I won't be able to honor your request for further compensation, please know that I shared your feedback with the appropriate teams.
We appreciate your business and look forward to providing you with the service you deserve on a future United flight.
Regards,
Liz
Customer Care"
And with that, any hope of me flying United ever again has completely disappeared. I don't think they will miss me, and I definitely won't miss them. Oh well I guess.
