American Airlines Sought Seat Give-Ups on Las Vegas Flight at 114°F as Heat Thins Takeoff Air

Summary
114°F heat in Las Vegas prompted American Airlines to offer compensation on a July 24 flight so some passengers would give up seats, reducing aircraft weight for a safe takeoff.
Hotter, thinner air cuts wing lift and engine thrust, forcing airlines to trim passengers, cargo or fuel, delay departures, or wait for cooler temperatures—especially at high-altitude or short-runway airports.
FAA limits vary by aircraft, weight and airport altitude rather than a single temperature cutoff, but researchers projected some airports could face weight restrictions on 10% to 30% of hottest-period departures by midcentury.
Phoenix has averaged 43 days a year at 110°F since 2020, while Las Vegas averaged about 18 such days from 2020 to 2025, trends researchers link to climate change and more frequent future disruptions.
