Sorry if this has been discussed before but I couldn't find it from the search engine.
Just a question that has been bugging me. When someone is cashing his/her miles to fly on other carrier (i.e.. Cashing UA miles to fly SQ/TG). Does that mean UA is paying the other carrier for the award seat it gives to the FFM members?
If that was the case, does it mean that UA is paying full-fare for the particular seats? Or do they have agreement that they don't have to pay as much? Partial may be?
