You're right. KLM starts using Dallas
as its second hub in the US (beside
Detroit - in conjunction with Northwest)
You can visit www.klm.nl to see KLM
most updated timetable, it starts new

The 747-400 was most probably at DFW on Sunday becasue IAH was shut down for weather, and many aircraft had to divert. I was stuck in San Antonio, and there were a lot of diverted aircraft on the ground.
