At a glance
On-site rentals at SeaTac's Consolidated Rental Car Facility (RCF) are more convenient but carry higher mandatory taxes and airport fees (such as a 11.1% airport concession fee and a $7.00 per day Customer Facility Charge). Off-airport agencies located outside the facility generally offer lower base rates and bypass several airport-specific surcharges, though they require separate shuttle transport that can add 15 to 25 minutes to your travel time.
