Whether veterans get free checked bags depends heavily on their current status and the specific airline. In 2026, most major U.S. carriers like Delta, United, and American Airlines provide generous free baggage allowances (usually 3 to 5 bags) for active-duty military traveling on orders or for leisure. However, for retired veterans or those who have separated from service, the benefit is not a standard industry-wide guarantee. Many airlines extend this perk to veterans only if they hold a specific co-branded airline credit card or have attained elite status in the frequent flyer program. Some carriers, like Allegiant or Southwest, are more veteran-friendly; Allegiant’s "Honors" program offers two free checked bags for all veterans with a valid DD214 or a veteran designation on their driver's license. Always check the airline's "Military Travel" page before booking, as you may need to verify your status through a third-party service like ID.me to unlock these specific cost-saving benefits on your flight.
