conspiracy theory
For the conspiracy theorist - what if AZ is making this tough with the hope of provoking rude calls, angry letters and media inquiries. Maybe AZ wants everyone to flood its call centers, spam its email servers and complain to its business partners such that it can finally announce that it must cancel all these tickets.
AZ might claim it tried to do the right thing, but people were not happy with just getting a $33 BIZ fare, were not willing to wait a bit while AZ worked out the rebookings and continued to gleefully reign terror and cost upon poor struggling AZ, proving again that no good deed goes unpunished.
As such, AZ would claim no option but to cut its losses and go back to selling tickets at normal prices.
Just throwing out a consipracy theory, no basis in fact, and certainly no desire to see such a thing happen.
