Southwest plans to reduce capacity, reevaluate 2024 financial outlook on delivery delays from Boeing

Shares of Southwest are falling in Tuesday premarket trading as the airline said that it plans to reduce capacity and reevaluate its full-year financial outlook because of fewer expected aircraft deliveries from it supplier, Boeing.

Southwest Airlines said in a regulatory filing that Boeing expects to deliver 46 737-8 planes this year. The company previously anticipated 79 737 Max aircraft deliveries, which included 58 737-8 planes.

In addition, Southwest said that it now assumes there will be no 737-7 aircraft deliveries, and it continues to assume no -737-7 planes will be placed into service this year based on the current certification status with the Federal Aviation Administration.

For the first quarter, Southwest now foresees operating revenue per available seat mile being flat to up 2%. Its prior forecast was for the metric to be up 2.5% to 4.5%. The company predicts economic fuel costs per gallon will be in a range of $2.95 to $3. That's higher than its previous estimate of $2.70 to $2.80.
