Yes. Usually three per seat per day in NYC. (JFK at least, unsure about LGA, and unsure how they’ll do it with codomicile). Picked in reverse seniority order. Limited to 3 times in a block of reserve and 10 times per month. Duty while on airport reserve is 8 hours.

FWIW, I had the seniority as an FO to completely avoid airport reserve after 2-3 months.
