After a chaotic six weeks, the brouhaha around fare combinability has simmered down. American, Delta and United have settled on a middle ground, but differed in how they got there. The bottom line seems to be that fare combinability again is permissible for circle trips and when stringing together multiple one-way fares, except for the very lowest fares. That means higher fares than before on certain itineraries but not nearly as high as they had been when airlines first enacted changes.
TMC executives said the issue appears to be resolved . . .
