Revenue rises without more passengers
Executives at Delta Air Lines, United Airlines, American Airlines, Southwest Airlines and Alaska Air Group have emphasized protecting margins over growing passenger volumes, NBC News reported, citing Reuters. Across the five carriers, passenger revenue rose nearly $8.8 billion, or 18%, in the third quarter from a year earlier, while traffic increased less than 1%.
United's commercial chief Andrew Nocella said the carrier's leisure load factor fell 1.3 percentage points in the quarter, describing the decline as a trade the airline would make every day. American finance chief Devon May said its less-full planes were a deliberate result of pricing decisions. Neither executive's comments were disputed in the report.
Fuel costs pressure forecasts
Gulf Coast spot jet fuel prices rose from $2.43 a gallon before the US-Israeli war on Iran began in February to $4.63 on October 20, according to Energy Information Administration data cited by the report. Delta and Southwest have cut annual earnings forecasts, and American expects a full-year loss despite higher passenger revenue.
US air fares rose an average of nearly 23% year-on-year in the seven months through September, against a 3.6% average increase in overall consumer prices, Labor Department data showed. JetBlue initiated a $10 one-way domestic fare increase on Wednesday, JP Morgan said, following a United-led increase the previous week that Southwest matched.
