The queue was very long, and they tried to upsell too much.

Went there after 9 PM, no queue

Returning the car with Avis was pretty easy. Sometimes, if you rent from younger staff, they might suggest upgrades. For an extra $10 a day, I upgraded to a GMC YUKON, which was worth it. But occasionally, you get an older staff member who doesn't offer upgrades and lacks knowledge. They equated a Ford Expedition with a Chevrolet Tahoe, which is clearly smaller. While the Expedition handles better, if handling was my priority, I wouldn’t rent the largest car. The office staff were generally friendly, but the Mexican or Asian staff inspecting cars at the parking lot were quite arrogant. Definitely a bad experience. Why put on airs when you're just inspecting cars? I will never rent from Avis again. Most expensive, yet the service isn't that good!

Picking up the car in San Francisco was very convenient, possibly because it was early and there were no queues. Chrysler's Town and Country has immense space; it fit our group of 5 people, 5 large suitcases, and 2 small suitcases. Truly an American car—big!

All rental companies at San Francisco Airport are in one location, making it very convenient. Plus, AVIS car pickup is on the first floor, which is great. The first staff member we met insisted there were no Mustangs and kept pushing us to upgrade. We went to the car lot and saw numerous Mustangs, so we talked to a different staff member and finally got a Mustang! Los Angeles Airport is not like this – each company is quite far from the others.
