DutchDeltaDude(nice name btw),
There are already 2 dailies to IAH from AMS, I am not sure Texas needs a 3rd daily to The Netherlands. I am sure if anybody from the Dallas/Ft.Worth area needed to get to AMS or anybody from The Netherlands needed to get to the DFW area, they would go through IAH, and evidently, the need for DFW service is not strong enough to warrant a DFW flight.
What I am surprised about is how DFW-MAD is untapped. I wish Iberia or American would step in and connect two oneworld hubs.
Give me a break, I created this username when I was a kid...
