Source: FlyerIntel analysis of US DOT BTS data · July 2023 – July 2026 · “Usually departs” is the scheduled time each flight number most often had over the period; airlines retime flights, so confirm the time on your booking. Flight numbers with fewer than 90 operations on this route are left out. This is history, not a forecast for your flight.

How this was worked out

Peak departure hourFlyerIntel data · Your departure hour is among the busiest at LGA, so check-in, bag drop and security all queue at once.+20 min

What this does not include.

FlyerIntel cannot currently obtain live security wait times for LGA, so this figure does not account for the queue on the day.
It does not include your journey to the airport, parking, or a shuttle from a remote lot.
International departures, and travel with children, checked pets or special assistance, need more time.
