97% of America's Red-Eye Flights Take Off in the West, and Overnight Flying Is at a Record High, 26 Years of Federal Data Show

Champion Traveler analysis of every US domestic flight since 2000 finds red-eyes concentrated in the Pacific and Mountain time zones, growing, and more reliable than daytime flights

SOUTH JORDAN, Utah, Sept. 10, 2026 /PRNewswire/ -- About one in sixty US domestic flights is a red-eye, and 97 percent of them take off in the western United States, according to a new Champion Traveler analysis of 26 years of Bureau of Transportation Statistics flight records.

The study counted every scheduled domestic flight reported to the federal government from 2000 through 2025 and classified as a red-eye any flight scheduled to depart between 9 p.m. and 3 a.m. and land between 3 a.m. and 10 a.m. local time. In 2025, 115,580 of 6.9 million flights met that definition.

Key findings:

• Red-eyes are a western phenomenon. 97 percent of 2025's overnight flights departed from the Pacific and Mountain states plus Alaska and Hawaii, a share that has never fallen below 95 percent since 2000.
• The red-eye is at a record high. Overnight flights grew 54 percent, from 75,158 in 2000 to 115,580 in 2025, after a low in 2009 and a collapse in 2020.
• Anchorage is the red-eye capital by share: 26 percent of its departures are overnight flights. Los Angeles leads by count with 19,064. Las Vegas flew the most red-eyes in America in 2000, lost more than half by 2010, and has since recovered.
• The middle-of-the-night departure is disappearing. Flights leaving after midnight were 31 percent of red-eyes in 2000 and 14 percent in 2025.
• The legacy airlines lost the overnight market. American, Delta and United flew 97 percent of red-eyes in 2000 and 64 percent in 2025. Alaska Airlines is now the most red-eye-heavy carrier, and Southwest, which flew none for 25 years, took 5.6 percent of the market in its first year.
• Red-eyes are more reliable. In 2025, 82.4 percent arrived within 15 minutes of schedule, against 77.6 percent of other flights, and they were cancelled less often.

The geography has a simple cause. An overnight flight from the West Coast crosses three time zones and lands on the East Coast at breakfast; the same trip westbound would land in the middle of the night, so airlines schedule almost no overnight flights in that direction. Among the 300 busiest red-eye routes in the study, 82 percent land in the Central or Eastern time zones.
