• LaGuardia Airport was closed for hours after an Air Canada plane crashed on Monday.
• More than 600 flights were canceled affecting thousands of travelers at 74 other airports.
• Some flights also turned around and returned to their origin.

More than 600 flights were canceled after an airplane crash at New York's LaGuardia Airport on Monday.

A Business Insider analysis of Flightradar24 data showed how the incident affected thousands of passengers at 74 other airports in the US, Canada, and the Bahamas.

We created a map showing the scale of the disruption at a time when travelers also face long lines due to TSA staffing shortages.

LaGuardia saw nearly 33 million passengers last year. While smaller than nearby JFK and Newark Liberty, it's still one of the country's busiest airports.

It primarily serves domestic routes as well as some short-haul international ones.

The map shows the range of Monday's intended routes — as far west as Denver, as far north as Bangor, Maine, and as far south as Key West.

Chicago O'Hare Airport faced the most disruption, as it had 39 flights to or from LaGuardia that were canceled.

It was followed by Boston Logan's 30 such cancellations and Toronto Pearson's 28.

The data do not include 18 flights bound for LaGuardia that diverted elsewhere.

While 10 of these landed nearby, others were forced to return to their original locations.

For example, an Air Canada flight U-turned over Poughkeepsie, in the Hudson Valley, before returning to Toronto.

LaGuardia Airport reopened with limited flights around 2 p.m. Monday, some 14 hours after the collision.

Air Canada Express Flight 8646, from Montreal, had just touched down when an airport firefighting truck began crossing the runway.

Both pilots of the CRJ900 were killed, while dozens of passengers were taken to the hospital.

The National Transportation Safety Board is investigating the incident, assisted by the Transportation Safety Board of Canada.
