Yeah this is gonna get interesting when they go away........the pilots who fly them love to fly them, hence why they are called the "atari ferrari". They are what DL has used for years and years from ATL-JAC and I am not sure what else with high capacity has the ability to fly that route. In fact the ONLY 3 planes I have ever seen fly that route in the last 10 years are the 757, A319, and E175. I remember probably 12 or so years ago DL went through a phase where they flew a 737-700 ATL-JAC before they retired those.
