I would like to add my 2 cents that these Embraers with F/C are fantastic - even coach is not bad. I use CO often for TATL flights, but I usually use NW to get to/from EWR because of the awful RJs that CO flys. Somehow CO ended up with the worst of the worst. Their RJs are not only cramped, but they seem to always smell of LAV. I would consider CO as my primary carrier now that DL/NW are merging, but I just can't handle all of my initial outbound and final return segments on their RJs. It is particularly insulting after hours in BF on a TATL flight to end up those last few hours on one of their RJs. They really need to upgrade the RJ experience.
