Ralf, how are you this morning ??
I am happy to see that CO still plans to operate this flight, at least that would give us entrance to the Presidents Club at Houston as well.
On the other hand, people at KLM told me some time ago, that flights to Chicago and Houston are the emptiest of all KL transatlantic flights.
But with fares from NLG 11000 for a RT WBC ticket from AMS to IAH, they can operate with noone in the back of the bus...and make some euros !!
