Frontier Airlines, the largest ultra-low-cost carrier in the U.S., reported a 71% increase in airfares for the third quarter, with losses widening to $104 million. The company's average ticket revenue per passenger was $67.82, while total revenue (including baggage fees, etc.) rose 30% year-over-year to $138.22. Despite the price hike, passenger numbers grew 18% to over 9.8 million. However, soaring fuel costs, up 82% to $425 million, led to the expanded loss from $77 million in the same period last year. Frontier anticipates achieving adjusted profitability in the fourth quarter, with its stock price rising approximately 6% in early Wednesday trading.
