Was supposed to be on UA855 LIM-IAH, departing LIM on 18 November at 1:50am, but received a text message at 21:30 that the flight was delayed until 15:00 on 19 November because the flight crew wasn't in Lima. There was no option to rebook on that 15:00 flight, and I have no idea why. UA automatically rebooked us on the flight departing on 19 November at 1:50am. We were offered a $15 food voucher for use at airport restaurants. This was a 24-hour delay in departure. I'm not sure how $15 is supposed to be sufficient for 24 hours for those without access to the airport lounges. Fortunately, we had access because we were traveling in Polaris Business Class. I asked for financial compensation to cover additional expenses incurred (extra night in our accommodation, plus meals). Denied. Instead we were each given $650 travel certificates and 5,000 miles. I'm no expert, but I don't think hotels or Airbnb's accept UA travel certificates. I tried explaining this to the chat agent when requesting actual financial recompense. The whole conversation was insulting.

On the second leg of our return home, the flight from IAH-RDU we had 1C and 1D. The system automatically bounced us from those seats to PE because 1C was allegedly broken. After some discussion with the GAs, we were kept in our booked and paid class. A very kind gentlemen accepted $500 in compensation from the GAs to move to Economy Plus.

I've submitted a complaint/request to customer care asking for reimbursement of expenses. Waiting to hear back, but not holding my breath.
