Alcohol is the biggest source of in-flight revenue for U.S.-based airlines
Forget movies and the array of in-flight snacks available: alcohol is the biggest moneymaker on airlines based in the United States.
A new study by the technology company GuestLogix reveals that of the 8 million in-flight transactions studied, the combined sales of liquor, wine and beer earned the airlines more than $43 million over the course of four months.
Flyers clearly like spirits best. Hard liquor accounts for 34% of sales, followed by wine at 13% and beer (10%).
The travel industry site Skift notes that travelers to Las Vegas spend the most on drinks and those heading to San Francisco and Seattle spend the most on food.
As for non-alcoholic beverages, they only made up about one percentage of all drink sales.
