Can I use my military spouse card to check in to the airport?

No, a military spouse card is not typically accepted as a valid form of identification for airport check-in. The Transportation Security Administration (TSA) requires travelers to present a government-issued photo ID, such as a passport or a state-issued driver's license. However, military IDs can be used for check-in if you are traveling on military orders. Always check with your airline and the TSA for specific requirements before your flight.
