well no, you said A and D they are both "up fares" just different products one is Business Class the other is first class. your fare was probably actually a B fare or an M fare your fare basis code should probably be buprl or muprl. when you're rerouted there really is no refund that can be given, the only other option would have been a full refund of your ticket if your flight was cancelled or delayed for more than 90 minutes. which you probably would have paid twice as much on another airline to get to your destination. I would take the reroute and the $100.
