So happy to find this thread! So here we go:
United GVA-LHR-NYC, connecting flight cancellation on thursday afternoon, got hotel till Sunday, 600 Euros cash, and refund for kosher meals I had to get. I was also told that I can book a hotel in the city for Shabbos and that I would be reimbursed, ended up staying by friends.
United NYC-CDG, denied boarding exactly an hour before flight. Rebooked on a direct flight and got there earlier than expected. Ironically checked in less than an hour before the flight! $150 voucher.
United NYC-GVA, passport problems with family for 45 minutes, missed check in. $600 voucher for each person.
United NYC-GVA, one hour delay. $200 voucher.
British GVA-LHR-NYC, second flight canceled twice, got to final destination an hour and a half later. $250 pounds were given to me immediately before boarding the first flight and $80 later on.
That's only the past 6 months or so, apparently I deleted the previous emails. Got a bunch of vouchers for delays and kosher food as well as suitcase replacements.
