American Airlines Group Inc. and Southwest Airlines Co. are taking a cautious approach to their third-quarter flight schedules as the coronavirus pandemic worsens in the U.S.

Bookings have stalled in July with the rise of virus cases, Southwest said Thursday, vowing to adjust its flying “aggressively” to match volatile demand. American said seating will be down 60% this quarter compared with a year ago—only a modest improvement from its schedule in the depths of the crisis in the second quarter.

The plans underscore the long, choppy recovery ahead for U.S. airlines after a fledgling rebound in May and early June. Despite stepped-up efforts to tout enhanced cleaning procedures and require passengers to wear face masks, carriers from United Airlines Holdings Inc. to Southwest warn that the industry’s deep slump will continue as long as the pandemic is raging.

“We haven’t gone backwards, we have just lost our momentum is the issue,” Southwest Chief Executive Officer Gary Kelly said in an interview after the company reported earnings. “We didn’t schedule August and September for that. We scheduled as if we were going to continue our momentum. We’ve got too many flights in August and September, and we’re going to be working on that. We’ll be pulling the schedule back.”

Cash Burn

Southwest fell 2.7% to $32.41 at 10:16 a.m. in New York. American slipped 1.3% to $11.21.

In the current quarter, Southwest will burn about $23 million in cash a day, about equal to the rate in the previous three-month period. Cash burn has become the most closely watched gauge for airlines as they struggle with the pandemic-induced collapse in demand that began in March.

About 27% of Southwest’s workers have agreed to leave or take extended time off, and the airline is now looking for more opportunities to cut costs. Because of the strong employee response, Dallas-based Southwest said it doesn’t plan to lay off workers or cut their pay through year-end.

That benign outlook contrasts with rivals that have warned that jobs could be at risk in October, once limits under federal aid packages expire. Southwest has received $3.2 billion in U.S. assistance from the Cares Act.

American has notified 25,000 employees, or 29% of its U.S. workforce, that they could lose their jobs later this year as the pandemic continues to damp demand. Another 3,000 people at two regional airlines owned by American also received notices of possible layoffs.

The Fort Worth, Texas-based airline has culled more than $15 billion from its operating and capital budgets this year, helping pull its daily cash burn down to $55 million in the second quarter—lower than a previous forecast of $70 million. American said it consumed about $30 million a day in cash last month.

American swung to an adjusted loss of $7.82 a share in the second quarter, compared with a $7.95 average loss estimate from analysts surveyed by Bloomberg. Sales tumbled 86% to $1.62 billion, better than the $1.43 billion expected by Wall Street.

Southwest posted an adjusted second-quarter loss of $2.67 a share, better than the $2.77 average loss estimated by analysts surveyed by Bloomberg. Sales plunged 83% to $1.01 billion, higher than the $904.2 million expected by Wall Street.
