[snip some of Jon & Marty's comments for length]

What market are you referring to? Flights of 3 hours or less? There
are a lot of flights on the majors from 1 to 3 hours and they are not using
regional jets on all of them. I've flown DEN to SFO/SJC on everything from
737/A320 up to 777 and 747. My last flight, scheduled for 1:20 was on a
737.

That's because 1) Denver is a major hub for United and 2) the 777 and 747 were
either being repositioned or Denver was an interim stop for a longer flight.
For example, I've been on 747 DEN-ORD that was 70% empty. Why? Because it
was the aircraft for ORD-Frankfurt or similar. Or it was used for
JFK-DEN-SFO-Sydney, etc.
