Do you earn 1 or 2 qualifying flights if there is a stop without change of aircraft?
On a normal connection, e.g. CPH-ARN-ORD, you would be credited for 2 one-way flights for qualifying purposes. But what about flights with stops that have the same plane and same flight number on each leg, e.g. SK4576 TRD-BOO-TOS?
Moreover, assuming that flying both legs of such a flight would only earn 1 one-way flight credit, what if you bought two separate tickets for each of the legs separately? Would this allow you to earn 2 flights? Certainly you would have to deplane and reboard again, which I assume would not be a problem.
