According to analysts at Jefferies, the rise of weight-loss pills in America could lead to significant savings for airlines. They suggest that a 10% reduction in average passenger weight might result in a 2% total aircraft weight savings.
This could translate into lower fuel costs by as much as 1.5%. Fuel costs are the largest single expense for airlines, making these potential savings noteworthy.
Jefferies projects that the four largest U.S. airlines—American Airlines, Delta Air Lines, United Airlines, and Southwest Airlines—are set to use around 16 billion gallons of fuel in 2026.
The average fuel price is expected to be $2.41 per gallon, leading to a combined fuel expenditure of nearly $39 billion. This figure represents almost 19% of their total operating expenses.
A reduction in passenger weight could also enhance the airlines' earnings. Jefferies estimates that a 2% decline in average passenger weight may lead to a 4% increase in earnings per share across the major airlines.
Specifically, Delta could see a 2.8% rise in EPS, United may gain 3.5%, Southwest could increase by 4.2%, and American Airlines might experience an impressive 11.7% boost. This is largely due to American Airlines having greater operational leverage regarding fuel costs.
Weight is a critical factor affecting fuel efficiency in aviation. For instance, the Boeing 737 MAX 8 has an operating empty weight of approximately 99,000 pounds.
It can carry about 46,000 pounds of fuel and 36,000 pounds of payload. When considering a two-class configuration accommodating 178 passengers, their total weight contributes significantly to the aircraft's overall weight.
Jefferies highlights the importance of passenger weight in fuel savings. A 10% decrease in average passenger weight could lead to a total drop of around 3,200 pounds, which is about 2% of the maximum takeoff weight for the 737 MAX 8.
This change could result in considerable fuel savings over numerous flights throughout the year. The focus on weight savings is not new; airlines have historically made efforts to reduce weight through various means, such as switching to lighter materials for in-flight magazines to save fuel.
As the popularity of weight-loss treatments grows, airlines could see added financial benefits from these changes.
