Bajrama who checked us in was super helpful, great customer service, attentive to our needs.

Very easy, great communication.

They said it was a free upgrade with no extra charges, but they debited over 1000 RMB from my credit card.

Long lines and few agents, waited for a long time. When it was finally my turn, they wanted to charge extra for a car with GPS because of the sound system. I refused and had to wait another 20 minutes for the manager. They first gave me a Prius, which I refused again, then the manager spent another 20 minutes to get me a Chrysler 300 with GPS.

Maybe because it was a holiday, but I waited in line for half an hour.

Checking in was extraordinarily slow, as there were only two people in front of me in line and it took over half an hour.

The Pick-Up instructions for ORD are misleading: "From the terminal, you can see the shuttle bus pick-up area. Take the shuttle bus to the store and check in at the counter" ORD has a tram to get to the car rental lot from the terminals; only airport hotels have shuttle buses. Please correct the instructions to indicate that travelers should take the tram.
