Southwest Airlines' Red-Eyes: How The Carrier's Overnight Network Works In 2026

Southwest Airlines is expanding the idea of “nocturnal silence” into true round-the-clock flying, reshaping how its Boeing 737 fleet is scheduled. For decades, the carrier kept its aircraft parked overnight, avoiding red-eyes used by many legacy network airlines. That changed with the launch of its first overnight services on February 13, 2025, starting with five daily overnight departures from Las Vegas (LAS), Los Angeles (LAX) and Phoenix (PHX). Routes included nonstop late flights to BWI and MCO, among others, and the program expanded to Hawaii by April 2025, reaching 33 daily overnight flights by June.
