Topic FAQs
Why does Budget rank #1 for this CONRAC list?
Budget earns the top slot from verified review aggregates, Kayak pricing bands, skip-the-counter eligibility, and CONRAC fleet depth --- not location, since all 12 brands share the same shuttle.
Are off-airport discounters cheaper than CONRAC?
Base rates may be lower off-site, but double-shuttle legs and opaque surcharges often erase savings --- especially for tight connections under 90 minutes.
How does Enterprise compare to Budget on deposit holds?
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://seatacrentalcarfacility.com/en/agencies before booking.
What is the Kayak average at Sea-Tac CONRAC?
Kayak 72-hour snapshot averages ~$57/day before CFC and ACRF. Compare all-in totals, not headline $/day, across Budget, Enterprise, and peers.
