I fly for Lakes out of ORD, so I'm not current on loads out of Denver. But, we have a very liberal jump seat policy and will take as many jump seaters as we have open seats in the back. Also, we are now flying the 1900's exclusively so there is no actual upfront jump seat.
Now would certainly be a good time for other airlines to lighten up on their 1 jump seater per flight policies. It's ridiculous to leave the gate half full with jump seaters left behind. With all the chaos in teh industry right now, this is one area where we could help each other out.
