The deliveries include 16 leased aircraft, the U.S. carrier said, adding that it expects the MAX to return to revenue service in March after all active pilots have received updated, MAX-related training.
"Given the continued surge in COVID-19 cases and depressed revenue environment, the company continues to experience softness in leisure passenger demand and bookings for December 2020," Southwest said in a regulatory filing.
The company also flagged elevated levels of trip cancellations for December travel.
Southwest now expects average daily core cash burn to be about $12 million in the fourth quarter, up from a previous estimate of between $10 million and $11 million.
Several U.S. airlines have raised their daily cash burn forecast due to this year's coronavirus-driven collapse in travel, as a batch of new lockdowns and advisories discourage Christmas and New Year flying.
