Arriving at an airport late at night for a relatively short overnight flight means you're unlikely to get much sleep. At the best of times, red-eye flights leave you tired, dirty, groggy, and unproductive the next day. But what if the times are even more extreme than normal?

Extreme red-eye flights

Looking at US domestic flights departing between 00:01 and 02:00 and arriving between 03:00 and 06:00, we see that there are 126 flights in the week starting December 3rd. It varies from a mere 12 on the 8th to twice as many on the 6th.

Some 25 routes are involved, reducing to 21 at airport-pair level if airlines are stripped out. The average sector is 1,241 miles (1,996km) with an average block time (including flight time, taxi time at both ends, and time for short delays) of two hours and fifty-nine minutes. Twelve airports have them, and Las Vegas, Phoenix, Los Angeles, Portland, San Francisco, and Denver have the lion's share of flights.

In the examined time period, the first 'extreme' red-eye service is American from Los Angeles to Dallas, an A321 that departs at 00:06 and arrives at 05:00. The last departure is Delta from Anchorage to Seattle, a B737-900ER that leaves at 01:30 and arrives at 06:00, just making it into the list.
