It boggles my mind that they would up a fight with an Ulti, by offering 4% compensation for what is basically the functional equivalent of a downgrade and then after fighting admit that it is embarrassing. Even then they came back with just a 14% monetary value in the form of a voucher, rather than actual cash. Given that an Ulti customer is typically one of their most frequent flyers, there is pretty much a guarantee that whatever revenue they lost would have been made up quickly. Offering a 25%-30% voucher at minimum would build some level of affinity too. I get following the "embarrassing" procedure with flyers who go once a year, but treating your "best" customers like this is just ridiculous.

At least they solved it to your somewhat satisfaction.
