Looking for some help on this. I was due to fly BDA - JFK - LAX - LAS and I upgraded the JFK-LAX leg to first class with a BXP1 certificate. The BDA-JFK flight got cancelled and I missed the connection so they rerouted me BDA - JFK - LAS in business class which I had already paid for. Does anyone know how if I will be refunded for the business extra upgrade and how I go about doing that?
