What are the security deposit amounts, credit card hold timelines, and modern payment options at the SeaTac Rental Car Facility?

At the Sea-Tac Consolidated Rental Car Facility (CONRAC) at 3150 S 160th St, SeaTac, WA 98188, all 12 on-site brands place a security authorization hold—not a separate charge—on your payment card at pickup. For standard short-term rentals paid with a major credit card (Visa, Mastercard, American Express, or Discover), the hold equals your estimated rental total plus a $200 security deposit. Two scenarios trigger a higher threshold: rentals of 4 or more days, or payment with a debit card. In those cases, expect the estimated charges plus a $250 to $300 deposit. Brand-specific floors also apply—Alamo posts a $200 credit hold or $500 debit hold (with round-trip flight proof), while Enterprise requires $300 for most vehicle classes and up to $850 for luxury and performance categories. Luxury, SUV, and specialty vehicles may carry even larger holds regardless of card type. Credit card holds are temporary blocks on your available credit limit. After you return the vehicle with no outstanding charges, the rental company releases the authorization; funds typically reappear within 3 to 5 business days on credit cards, though bank batching can extend release to 5 to 14 business days. Debit card holds draw directly from your checking balance and may take up to 10 business days to clear. Regarding modern payment methods: CONRAC rental counters do not accept Bitcoin, Ethereum, or other cryptocurrency at pickup. Apple Pay and contactless wallets are generally not supported for deposit authorization—you need a physical or digital card tied to a Visa, Mastercard, Amex, or Discover account in the renter's name. Third-party booking platforms such as Qeeq may let you prepay base rental fees with BTC, BCH, or ETH through BitPay (with a 15-minute payment window and at least one day before pickup), but you must still present a qualifying credit or debit card at the CONRAC counter for the security deposit hold. Cash, prepaid gift cards, and wire transfers are not accepted for deposits by major brands. Verify your brand's exact hold amount on your rental contract before leaving the counter.
