If you can't get EWR 737 out of BI just bid any 737 and you will get EWR in the next vacancy.
That's a big assumption on the 321. I could see the back side of the clock, min credit 3-days getting old really quick. For Dafuq, the main difference isn't between the bid awards on the two fleets in terms of scheduling, it's what happens afterwards. Bigger fleet means more open time, which means more flexibility in moving your schedule around. Trades are still subject to seniority, but there is just more parts to be able to piece together.
