I was the plug for a time on the NY 765 4-5 years ago, and I typically did 3 SC and 2-3 trips a month, with some variance but not much. Almost all 3-day, 44-50 hour TAFB. Glorious. I never got forced into a line, FWIW.
The only downside was the 2-day non-commutable domestic trans cons that started one winter, then came back permanantly the second winter. Non-commutable on both ends. If you live in NY, it’s great. If not, it sucked bad. They were always in open time. A lot.
I have no idea what the current bid packet has, or what network has planned. I left before the cabin upgrades, so maybe someone current can help out with how network has been using them, of if there are any rumors within the fleet. Good luck.
