CG, what I don't understand is why you lament what happened post 9/11 with RJ flying expanding at the expense of mainline but don't consider that with this TA you make that just as plausible a thing to do today as it was then.

50-seaters were profitable on 09SEP11, they're not now and wouldn't be even with 9/11 2.0. What is profitable now and post 9/11 2.0 would be 76-seaters.

If 9/11 2.0 happened today and Delta needed to cut capacity, they could cut a large portion of it from mainline without touching DCI, thanks to where the ratio minimum is set with c2012.

And fwiw, with DCI's current fleet is the C2012 ratio is 1.35, post TA2015, it's 1.35. The 1.56 and new 1.81 are not in play. In June we're slated, according to DALPA, to be at 1.6 on the ratio, 1.35 is the min, so you could cut about 120 mainline jets and furlough and never see another DCI jet get parked.

Adding more 76-seaters makes DCI more profitable. The wisest thing we could have done to save transferring flying from here to there was to make them choke on their 50-seat fleet, instead, we let them expand their 76-seat fleet.
