Delta Air Lines has swung back to profit.
Net income hit $652 million over the three months to the end of June.
That's its first profit since the global health crisis began, and the carrier says it now expects to stay in the black for the rest of the fiscal year.
Delta was helped by government support for workers' salaries.
But it also saw a real rebound in travel demand and revenues.
They hit just over $6.3 billion - way down on pre-crisis levels, but much better than in recent months.
Passenger numbers hit their highest since March last year, forcing U.S. carriers to hire more pilots and other staff to support the recovery.
Delta says it hired several thousand over the quarter, and is continuing to hire more.
The airline says corporate travel also improved, and could be 60% recovered by September.
Overall, Chief Executive Ed Bastian is encouraged.
Speaking to Reuters, he said the days of burning through cash are over.
