## At a glance

At SeaTac, renters aged 21–24 pay a daily young renter fee (typically $20–$30/day), while those under 21 are generally prohibited. Active-duty military or government personnel on official orders may rent at age 18 with a full fee waiver.

## What to know

At the SeaTac Rental Car Facility (located at 3100 S 160th St, SeaTac, WA 98188), age-based surcharges are strictly enforced by all major rental companies (Enterprise, Hertz, Avis, Budget, National, Alamo, and Dollar/Thrifty). For renters aged 21 to 24, a mandatory Young Renter Fee applies, ranging from $20 to $30 per day (e. , Hertz charges $25/day; Enterprise charges $22/day). This fee is in addition to the base rental rate, taxes, and optional insurance. Renters under 21 are almost universally prohibited from renting any vehicle class, with no exceptions for standard personal travel. However, a critical exception exists for active-duty U. military personnel and federal government employees traveling on official orders (e. , PCS, TDY, or official business). These individuals may rent at age 18 or older, and the young renter surcharge is fully waived. To qualify, the renter must present a valid military ID or government credentials, along with official travel orders dated within 60 days. Some companies also require the renter to be on the organization’s insurance or purchase a damage waiver. For example, at the SeaTac Hertz counter, a 19-year-old soldier on PCS orders can rent a standard sedan for $45/day base rate with zero young driver fee, whereas a 22-year-old civilian would pay $45 base + $25 surcharge = $70/day. This policy applies across all SeaTac on-airport rental brands, but off-airport locations may have different rules. Always confirm directly with the rental counter and bring original orders to avoid denial.
