I booked a paid first class ticket for today, for a two-segment trip. The second flight was cancelled so I am re-routed on two new flights. The first flight is first class but the second is coach.

The one-way coach fare (if I booked it today) for the second flight is about the same as the entire first class ticket that I had bought. But when I booked the ticket, FC was about $100 more than coach.

Do I have any hope of a partial refund or at least the EQMs or miles as though I had flown on the original FC tickets?

Thanks.
