I purchased IAH-IST round trip in comfort class. Now I see a schedule change in my record. Comfort class still offered on the outbound IAH-IST, but is no longer offered on the return IST-IAH. Instead, the system re booked my in economy.

I suspect this is part of TK's initiative to discontinue comfort class system wide.

What are my options? Can I ask to be placed on a UA flight via FRA? How about an upgrade to business on TK? Is this reasonable to ask?

Thank you!
