JFK-GYE will nearly always have an A321neo, as will TATL routes. JFK-LAX gets priority (I believe) for the NEO with Mint. As for other routes it is kind of hit-or-miss as it's relatively interchangable with the classic A321.

The A321neo has the same wifi as the A320 phase 2 refreshed fleet (the majority of 32M aircraft), as well as the A220 fleet. It is the ViaSat-2 system. The only aircraft that have the legacy ViaSat are the A321ceo (both with and without Mint), the E190, and the remaining classic A320s (320).
