Here are the 20 Southwest Airlines routes that will get red-eye flights

Southwest Airlines passengers will board red-eye flights for the first time ever beginning this February.

It marks a major scheduling shift for the carrier — one that comes amid a raft of other changes at Southwest as part of an operational shake-up meant to improve profitability.

Southwest’s first tranche of red-eyes will begin Feb. 13 on five routes. Each will land at its destination on the morning of Feb. 14.

By mid-April, Southwest’s red-eyes will be flying on a total of 20 routes — including five from Hawaii to the U.S. West Coast.

It’s an efficiency play by Southwest. The company said that adding the overnight flying — which will put planes in the air during hours that Southwest has typically parked them — will add the capacity equivalent of about 18 aircraft to its 2025 schedule.

Southwest detailed the decision during an investor presentation Thursday. It described the move as one that will “drive revenue without additional aircraft or headcount.”

So, where will customers find the new red-eye flights?

Baltimore/Washington International Thurgood Marshall Airport (BWI) will be Southwest’s top red-eye hub on the East Coast, with the airport set to have overnight arrivals from six destinations by early March.

Las Vegas’ Harry Reid International Airport (LAS) will have the largest bank of eastbound red-eyes, with flights bound for five destinations. The airport will also receive three of Southwest’s five overnight flights from Hawaii to the U.S. mainland.
