This may be a silly question that may have been covered before, but I haven't seen it. I'm wondering, if I am, for example, a DL Sky Miles member and want to claim an award on let's say OS, would it be harder for me to get a seat on a given flight as a DL ff member than it would be for a Qualiflyer ff member? In other words, do the airlines have one big quota for ff awards on each flight that is open to members of its program as well as members of the partner programs OR are there individual limits for each partner? I hope this makes sense!
