Just a few months ago US Airways started a bunch of new E70 service out of DCA to places like DTW, CLE, IAH, ..., etc. I was curious what sort of initial revenue/passenger load performance these new DCA flights might be having at this point if anyone knows? I see the fares to CLE are pretty solidly outrageous (except for Tues & Wed), so I'd imagine that generates some cash if they can take a nick out of the CO share of the market. However, with NW and especially Spirit on the DTW flight, I can't imagine revenues and yields on those flights are great. Can anyone shed some light on them for me, most specifically the DTW nonstops? Because if they're performing well and are going to stick around and not be cut from the route network with haste, I may use them.
