I'm not wrong. My point is not about the nature of the previous failed offers but what the new offer should have been - an increased amount and cash.
the offer is not just vouchers, it is about about providing reasonable alternative transportation.
given the flight is 5pm on sunday, there isnt any flight UA can put them on until 3pm on monday? There are even flights in the evening.
If UA can IDB for crew, it surely could oversold the evening flight on sunday, morning flight, noon flights on monday, or put them on AA in which it has an interline agreement. UA just doesnt care bcause it is cheap
