Whatever the reason for this surprise, it's fine by me. I'm mostly happy with delta as they offer me some good direct flights to AMS (my birthplace) and CDG and LHR. From there I can get to anywhere in Europe.
Next to that enough links to Asia as well.
I'm sure the surprises will end again, but as long as the package of flights stays the same its all good by me. Now if only they would offer a direct to CMH, that would be great! (are you listening Delta? )
