Cost at SeaTac CONRAC
Both Sixt and Avis operate from the consolidated rental car facility at 3150 S 160th St — identical shuttle service, airport facility charge (~$7/day), and concession recovery fees. The meaningful difference is base rate tier (Medium vs Medium) and how each brand prices SUVs, add-ons, and deposit holds.
For a typical 3-day sedan rental (2 travelers), Sixt estimates $205 all-in vs $205 for Avis. Family SUV trips widen the gap: Sixt $336 vs Avis $336 (4 passengers, 3 days).
