A frequent flyer program shines to be a must for an airline that wants to fly business people. They can collect miles for their private use and that's making them loyal to their airline.
So, no airline can be without a ff-program (except the no-frills). As they don't have another solution, they are still staying in the Qualiflyer-program until they find a better solution. LOT for example, is likly ot join the Star Alliance. After such a step, I think they will quit the Qualiflyer membership and join LH's Miles&More. But right now, they don't have a solution.
For Swiss, I think they will keep Qualiflyer for the future.
I think that we will see further consolidation in frequent flyer programms in the future. Today, almost every large airline has it's own frequent flyer program. Soon, we will have about 3-5 worldwide alliances. Each of them with about 5-10 members and about 2-6 ff-programs. This numbers may not be very exactly, but I think it gives a general idea.
Wouldn't it be nice if some of the airlines would give up their ff-programs and merge them, for example, there would be a Star Miles program instead of LH's miles&more and UA's Mileage plus. Of course, people can already exchange miles from the two programs, but with a merge of them, the marketing could be much more powerfull.
Swissair did somethink like that with their Qualiflyer Group, it was an alliance with just one ff-program. Of course, they failed and we know that story, but the idea of one ff-program for one alliance is pretty interesting.
What do you think? Do you think, we will see a consolidation of ff-programs soon?
