It's unclear to me from the Duffel page which scenario happens. https://duffel.com/flights/airlines seems to indicate some airlines have a direct connection, but the vast majority go through something called Travelport.
If I ask the airline to cancel my booking, what happens? Do they do so? Does the Duffel markup come back to me? Do I get status benefits from the airline?
