Choosing between Sixt and Avis at the Sea-Tac CONRAC? Both operate at the consolidated rental car facility — same free shuttle, same address (3150 S 160th St). The difference is price tier, loyalty bypass, and counter experience. ## Cost at SeaTac - Sixt: Medium tier · $205 est. (2p sedan, 3 days) - Avis: Medium tier · $205 est. (2p sedan, 3 days) ## Reviews - Sixt: 4/5 (134 reviews) - Avis: 4/5 (241 reviews) ## Convenience - Sixt: Express counter - Avis: Preferred counter bypass ## SeaTac Verdict For leisure travelers prioritizing value, compare deposit holds and base rates side-by-side.

Last verified 2026-05-26. * ## Cross-verification workflow Compare live inventory on Kayak, confirm Port construction advisories at portseattle. org, and verify mountain pass traction rules on wsdot. com before ski or national-park departures. Deposit holds ($200–500) release 5–14 business days after return depending on card issuer batching — not instant at drop-off. ## How rankings are computed Rankings combine verified Google review aggregates, Kayak 72-hour price hints, skip-the-counter program availability, deposit hold policies, and CONRAC-specific fleet rotation data from the Port of Seattle consolidated facility (3150 S 160th St, SeaTac, WA 98188, opened May 2021). ## Seasonal demand context January shoulder weeks shorten queues but may reduce adjacent service hours. Summer cruise overlap at Pier 66 and holiday banks compress shuttle capacity — book vehicle class 7–14 days ahead for AWD SUVs during Stevens Pass and Snoqualmie winter windows. CONRAC serves annual passengers (2024) across 12 authorized brands on 23 acres (LEED Silver). Facility charge ~$7/day; concession recovery 11.

Topic FAQs
Why does Budget rank #1 for this CONRAC list?

Base rates may be lower off-site, but double-shuttle legs and opaque surcharges often erase savings — especially for tight connections under 90 minutes.

Both operate at CONRAC with $200–500 typical holds releasing 5–14 business days post-return. Debit-card and prepaid policies vary — confirm at https://www.seatacrentalcarfacility.com/en/agencies before booking.
