I though Delta used to operate to FRA,LGW and ORY(or was it CDG?) from DFW, it's a shame why they stopped it. I think another DFW-LGW flight would work, AA and BA have high loads on that route and 2 out of 3 flights are 777's and the other is an MD-11. I think Delta would do well on it, I don't think it will happen though since Delta seems to be downsizing it's DFW hub.
Give me a break, I created this username when I was a kid...
