What is the difference between off-site and on-site rental car operations at SeaTac Rental Car Facility?

Detailed answer

At SeaTac Rental Car Facility, some rental car brands operate directly inside the off-site RCF building, while others are considered budget or independent brands that require a separate corporate shuttle pickup outside the standard airport loop. The on-site rental car companies, which include major brands like Alamo, Avis, Budget, Enterprise, Hertz, and National, have their customer service desks located inside the RCF building. In contrast, off-site or budget brands like EasyCar, Fox Rent a Car, and Payless Car Rental operate from locations outside the RCF and require customers to take a shuttle bus to their facilities. The shuttle service typically runs on a regular schedule, with waiting times ranging from 10 to 20 minutes. For example, the shuttle bus to the off-site rental car facilities operates from 5:00 AM to 12:00 AM, with a frequency of every 15-20 minutes. Customers can expect to pay a fee ranging from $2 to $5 for the shuttle service, depending on the rental car company. It's worth noting that the RCF is located at 18200 International Blvd, SeaTac, WA 98188, and is approximately 2 miles from the main airport terminal.
