I just spent two hours on the phone with Delta and KLM/AirFrance. This is the little I could find out. Delta was literally no help. First person told me they could only quote what was on their schedules and it didn't feflect any changes. The second person told me "it was against the law" for them to divulge who the contract carriers where. This despite the fact their web page lists who that is for the flights between LAX and PHX, and used to list Malev in Europe.
KLM/AirFrance at first didn't know what I was talking about. After they came to understand Malev was not the airport but rather one of their sub-carriers they looked further and told me AirFrance out of CDG was flying Airbus 320's to B-pest. I don't know how they can make any money doing this.
Then they told me that KLM was in fact flying their own 737's out of A-dam. I had to ask where they got all those planes that don't seem to show up on their inventory. Then they put me on hold. When they came back they admitted they had an e-mail from "corporate" that said these flights were being handled by alternate means and that "some re-routing" might be required. For all I know that means you could be flying Kasakhstan Air via Kiev to get to B-pest. Anyone else with any fresh info?
