There will be more movement on the E190 than the A320. JFK/BOS are about the same in terms of how many openings they will have. I'd expect E190 reserve to go 3-5 months as long as we keep hiring (big IF).

On reserve we work 18 days per month, so in a 31 day bid period you get 13 off. 12 off in a 30day bid. During the slow months (Sept-Mar) they typicall give you 1-2 extra days off (PRL days), which are paid. You have the ability to swap your reserve days around pretty easily using Flica, and can put in bid preferences for whatever you want.

You can put in preference bids the day prior to a RSV shift for trips that are open. That helps plan your commutes.

Both bases are very commuter friendly, just dont be stupid when planning your commutes.

There should be lots of openings on the E190, so I would shoot for that if you get to pick equip and want to hold a line ASAP.
