My 2 cents:
I could live with more 76 seaters if a far greater number of 50 seaters are parked and total RJ lift decreases and mainline lift increases - with the right deal. This mean no more seats, no higher MGTOW, just a few more 76 seaters.
I know allowing more large RJs is very distasteful, Me and 1100 of my closest buds had a unpaid vacation due to the RJ proliferation from 2000-2005, but times have changed.
We are hiring as fast as we can.
Guys are no longer stagnating at the regional.
Less RJ seats, less RJ Pilots is a good thing.
The Alaskan Code-share has withered.
Finally and by far most importantly, We have the C series order at mainline. The final lines of the RJ era have been drawn at 76 seats. We no longer have to worry about larger and larger RJs encroaching on mainline.
Lets not get hung up fighting the last war - RJs as an issue is dead - lets focus our efforts on JV scope and code-shares - that is were the section 1 threat lies in my opinion.
