I think this is a case of UA
trying to match capacity to demand.
Shortly before 9/11, UA
bumped their IAD
service to 3x a day on mainline. (LAX
was 3x daily for a short while as well, I believe.) I flew NRSA on those flights
often and loads were okay but rarely full. With AA
's dominance on the DFW
routes, my guess is that UA
got mostly DC-based FF
and Dallasites connecting to Europe
(in other words, not a huge share of the market).
More frequent service on smaller planes is probably the right answer for UA
in this market. And although I haven't flown on an EMB-170 yet, yes, thank you sweet Jesus it isn't another CRJ route.
Also, I'm sure the retirement of some of UA
's 737s is playing a role in this route. Didn't somebody say DFW
is the only UA
mainline city that has no UAX service? Interesting...
