I have a shorthaul bmi flight booked but I don't know what class the ticket was booked into.
I was wondering if there is any way to retrieve the booking class from the PNR.

Looking at my booking on flybmi.com, I can see:
Cabin : economy (flexible ticket)

Does that mean it's full fare Y?
Or do other flexible fares (with a charge) count as flexible too?

Thanks!
