The weather on the tarmac looks deceptively calm, but LaGuardia departures are already losing ground to the wind.
While surface sensors report zero-mile-per-hour winds and 10 miles of clear visibility under cloudy 58-degree skies, the FAA reports departure delays averaging 16 to 30 minutes due to wind conditions. At an airport where two short runways handle some of the densest air traffic in North America, what happens just a few hundred feet in the air dictates how quickly planes can roll.
What's happening
The FAA has slowed departure flows out of LGA, with outbound flights taking an extra 16 to 30 minutes to get airborne. The bottleneck puts an estimated 745 daily flights at risk of falling off schedule.
LGA relies on delicate runway interleaving. When winds aloft force air traffic control to route departures around specific approach corridors or switch departure headings, spacing between planes increases. The result is an instant queue on the taxiways.
What This Means
A 20-minute departure delay at 5:00 PM on a Monday rarely stays a 20-minute delay. Based on BTS data over the last six months, LaGuardia posts a 73.4% on-time departure rate. When flights miss their slots here, they average a 78-minute delay by the time they reach the gate.
If your flight leaves LGA late this evening, your arrival buffer disappears. The outbound queue is steadily absorbing the slack that airlines build into turn times, meaning aircraft scheduled for late-night return legs will feel the pinch.
What To Do
- Board on time. Departure delays mean planes wait in line on the taxiway, not at the gate. If your airline calls boarding, get on the plane.
- Check your inbound connection now. If you are flying out of LGA to connect elsewhere tonight, pull up your connecting flight. A 30-minute runway delay can break a 45-minute layover in Charlotte or Atlanta.
- Track your tail number. Use your airline's app to track where your specific plane is coming from. If the inbound aircraft is already at the gate, you only face the runway queue. If it is still inbound, your departure delay will likely grow.

Outlook
Because this is a metering issue tied to wind patterns rather than severe convective weather, planes are still moving. However, with the peak evening departure bank now pushing through 7:00 PM, taxi queues will likely expand before they shrink. Expect delays to linger through the rest of the evening push until departure volume naturally tapers off around 9:00 PM.
