This reminds me of a story I heard of a guy, working for Servisair at Oslo airport (Norway).
He was working on the check-in on an overbooked CO flight to Newark, and they needed voulenteers.. Three guys on a trip to Las Vegas were given the following offer (They were booked in Economy):
-Oslo-Stockholm on SAS, Business Class
-Stockholm-Newark on Malaysian, also in Business Class
-$800 per person in travel vouchers
-Arriving in Newark at 6 PM instead of 2 PM..
They turned it down, because one of the guys meant that it would make their three-night stay in NYC shorter...
