Free snacks are making a comeback in the main cabins of major U.S. airlines.
United Airlines flight attendants began passing out crackers and mini-pretzels on Monday.
Fort Worth-based American Airlines also announced Monday that free snacks will return for main cabin passengers. All of American's domestic flights should offer free snacks by April.
Dallas-based Southwest Airlines has always offered free snacks, as has Delta Airlines.
Many airlines, however, ditched free snacks to save money in the lean financial years after 9/11.
The return of free snacks comes at a time when many U.S. airlines are posting record profits.
