In general, I can. In LaGuardia? Aside from right after 9/11 and during COVID-19 when almost all commercial travel stopped, I cannot.

I don't think people saying this stuff quite understand how busy LGA is even at night. I'd even go as far as to say that three minimum on duty with two in the tower at all times (for a ground/air split), would be the bare minimum for any hour or situation at LGA.

It does quiet down eventually. There's no scheduled departures 22:55-5:45 and only a handful of arrivals 23:59-6:45.

However, arrivals stay pretty heavy right up until 23:59 even on schedule and if you've got a lot of delayed flights (not exactly uncommon at LGA) - you may still have a lot of departures going out in the 23:00 hour.

I would not be surprised to learn that they're staffed to an appropriate level for what the schedule says is supposed to be operating at that time, but a very inadequate level for what actually winds up operating at that time on many days.

Initial analysis suggests they were running about 75% of full capacity in flight ops in the 15min prior to the accident. I doubt they were staffed to 75% of the daytime peak.
