I opened a Navy Federal account at Subic Bay on my first deployment in 1985, back when if you were on the West Coast the only way you could open an account was when you were overseas. All the old salts had NFCU accounts and highly recommended it.
I keep some money in a local bank checking account for convenience, but the majority of my cash is still at Navy Federal even though the closest branch office is 1500 miles away. I can do everything I need to online.
Husband’s first car was financed through Navy Federal back in ‘73. Still have it open but have used AutoTruck (Ford) since leaving military in ‘79. Have never banked any where else! Daughter likes to use USAA.
