On hot days, flights experience weight restrictions. Focusing on five major aircraft at 19 of the world s busiest airports, researchers at Columbia University concluded that 10 to 30 percent of flights scheduled for takeoff in the heat of the day will have to reduce their weight by an average of about 700 pounds  or three passengers and their luggage.

For most airports, weight restriction days may increase to between 10 and 50 days a year by 2080. Airports in hot regions, at high elevations and with short runways will see the biggest changes. These include airports in Bangkok, Dubai, Miami, Los Angeles, Phoenix, Denver, Washington, D.C., and New York s LaGuardia.

Across all airports, restricted flights are predicted to increase by as much as 50 percent for large planes.
