Aeroplan J ticket for this am but plane was swapped for a dash 8 ( I didn't even know that they flew them out of NY) and no J class. No suitable alternatives because my timing is too tight today. What is procdure for comp?
I've done this for Aeroplan and cash tickets, and they've always come back with a fair refund amount for me (like the difference between what I paid and what Standard would have cost at time of ticketing). For Aeroplan, call Aeroplan after travel.
You could also probably write in about your displeasure and get a discount code or eCoupon as well.
