My brother flew from LAS to FRA via EWR on January 5 and had a terrible flight. On Friday 4th late evening his flight 50 EWR-FRA was cancelled and replaced with flight 1750 now using a PMUA 763 2-class plane but schefuled for the same departure time. When he arrived in EWR, 1750 had already been delayed because of aircraft servicing. Once boarding had been completed, the delay grew even bigger because maintenance hadn't repared the plane. BF cabin had to deboard again as mechanicsneeded to work on a piece below this cabin. That's when the mood in the Y cabin turned sour since many of those passengers wanted to deplane as well but were not allowed. An unruly passenger in Y started screaming he did not want to fly in a broken plane and that they were going to crash. He and his family were eventually removed from the plane by the captain and TSA. The flight left with around 3 hours delay. Unfortunately, the troubles did not end there. I suspect the plane was also seriously miscatered since passengers in the last few rows were not served a regular meal but only an inedible wrapped Cheeseburger (the same they sell on domestic flights?). Water supplies aboard were almost depleted once breakfast service started, most certainly because of water service during the delay on the ground. Breakfast service for the last rows of Y consisted of Crackers instead of the usual fruit/croissant combo (IMHO, the crackers can't be worse than the disgusting pastry they call croissant but that's another problem). The crew itself, it appears, did not have a stellar day as well. To be honest, I think he should be entitled to compensation, even though UA already sent a compensation offer for 7000 miles because of the cancelled UA50 he was originally booked on. What do you guys think? Would you write Customer care? Also, how is it even possible to miscater this flight on a smaller airplane than what originally was scheduled (764).
