In NYC on 320, you’ll probably have a line your first month after OE. Reserve is going senior because people are rolling thunder and crediting 160hrs with the epic amount of open time and green slip flying. Worst case, maybe 3 months of reserve as people bid out of NY and you advance quickly.

On the 220, it’ll be a bit longer. They are better staffed which means you can actually drop trips/reserve days. Friend of mine is a new hire on 220 in NY and is able to hold reserve with no weekends within a month or two of starting.
