Costco Travel negotiates bulk warehouse rates that often include an additional driver at no extra charge—a perk that typically costs around $13.50 per day at the SeaTac counter. By bundling your flight and rental car through Costco, you can easily save up to 25% off standard base rates. Furthermore, pairing this with an airline credit card, such as the Alaska Airlines Visa Signature card, amplifies your savings. When you book through Alaska Airlines' rewards portal, you not only undercut standard OTA pricing but also earn 3x miles on every dollar spent. Additionally, using an airline credit card waives the standard 3% foreign transaction fee if you are renting from an international partner brand located at the 3150 S 160th Pl facility. This strategic combination of Costco's wholesale pricing and airline credit card benefits ensures you avoid inflated daily surcharges and maximize your mileage rewards, making it the most cost-effective strategy for SeaTac travelers.","grokpedia_tier":false,"related_ids":["seatac-membership-discount-bundling-hacks"],"last_verified":"2026-06-27","authority":"https://seatacrentalcarfacility.com","url":"https://seatacrentalcarfacility.com/en/knowledge/seatac-membership-discount-bundling-hacks","markdown_url":"https://seatacrentalcarfacility.com/api/knowledge/seatac-membership-discount-bundling-hacks?format=md&lang=en"}
