Just imagine how much it would cost to book a same-day trans-atlantic flight for two people.
He would have zero choice in seating, so he would almost certaintly be stuck in a middle seat in pleb class. If he paid for the WIFI so he could read his thread here, then it is entirely possible that an eavesdroping neighbor could be reading it as well.
If his return flight was booked with Delta as well, he will also need to pay for short notice pleb class return tickets. At this point, he feels like he has to go because all of his accomadations are prepaid and nonrefundable.
The drunken hollerin' that got him kicked off the last flight cost him many thousands of extra dollars. In total, their sub-economy class flights and 1 star roach hotel rooms will cost as much as business class tickets, and 5 star accomadations.
