Budget staff at Seattle airport uses some manipulative tactics. First, they ask about the number of people and luggage, then tell you that the car you booked is not available and suggest you upgrade for double the price. After refusing, the staff claim the price includes full insurance and advise you to sign electronically to save time. If you trust them, you may fall for it, as I discovered the next day that they had added duplicate insurance, which cost almost as much as the car rental.

Didn't understand the charges, where did the extra $89.00 come from?

The attitude of Budget in Seattle was quite good. They might have realized we were returning customers through our conversation, so they didn't dare push additional charges.

Short wait time, but the service experience was very poor. The poor experience can be summarized in the following points. First: They kept trying to upsell more expensive models under the guise of fuel efficiency and more space. Second, they pushed for more expensive insurance. Third, after rejecting all these offers, they lied.

There were many people when picking up the car, but returning was quick (possibly because I had full insurance). The free shuttle was convenient, the return location was near a gas station, and the car was in good condition.
