Maybe I'm missing something, but according to GCmap this one is 1968. That would be longer than IAH-YYC...and every thing I've seen on that route for UA has been mainline, though AC does operate it as RJ service. In looking through the threads the only one longer I see is an AC flight YYZ-PDX at 2097.
