I have a flight booked in business class on Qatar Airways from CMB-DOH-JFK using Asia Miles in June. I’m thinking of changing my trip due to what’s going on in Sri Lanka but don’t want to lose my space in the DOH-JFK leg. Would Cathay agents let me change the CMB-DOH leg and keep the DOH-JFK leg? (And I assume I’d do this via Cathay agents and not Qatar agents, right?) Thanks for your help!
