Southwest Airlines just started selling tickets for 2022 travel and its website went down

Southwest Airlines opened its schedule for reservations through the busy spring break travel season early Thursday and its website apparently wasn't ready.

Travelers trying to book tickets for travel into April 2022 — the airline opens its schedule in shorter increments than most major airlines — were greeted with error messages on the airline's website and mobile app.

Southwest representatives on Twitter thanked travelers for their patience and said the issue was being worked on.

One error message: "We are unable to process your request. Please try again. If you continue to have difficulties, please contact a Southwest Airlines Customer Representative at 1-800-I-FLY-SWA (1-800-435-9792).''

"We're working with our technology team to get our website back up and running,'' the airline said on Twitter at 10 a.m. Eastern.

Southwest's website is often overwhelmed during busy booking periods, especially when the airline holds major fare sales.

Incoming CEO Bob Jordan, who started in the technology department at Southwest, last week said technology upgrades will be a priority for the airline.
