When flying out of my "home" hub of IAH, I always find it interesting to walk over to the International Departures Terminal D and see what's shaking. Well, while connecting from CLL-ELP late yesterday evening, I saw KL 664 departing from gate D9. I walked over there, aware that KL added another IAH-AMS flight a few months ago on a 767-200.

However, when I got to D9, I saw a 737 (I think it was a 700 series), with red-and-white livery, a red tail with a white cross (similar to the old Swiss logo), but it said something like Privt Air on the side. Is KL operating a 737 nonstop from IAH to AMS? Does anyone have any information on this flight?

I know that LH operates business-only 737's from EWR to DUS, but I wasn't aware of a similar situation in that market. I didn't see any indication that CO had a codeshare with their closest ally on the boards either. Thanks!
