* Booking: great experience. The person who picks up the phone is a lady who speaks English natively. She only asks for minimal information (phone number, time and place of pickup). By contrast, Lucky7 never had an actual person answer the phone - I called 3 times at different times of the day and got Padam Raghav's voice mail.
* Rates: United clearly lists their rates online at http://www.unitedcabco... (the standard $3 per mile, plus fees charges by the city of San Jose)
* Cab: friendly drive, drove well, no complaints. You can pay with cash or by credit card.
* Extras: I once lost my driver's license in a United Cab on my way to Hawaii during the winter holidays. I only realized that at the airport, and called them. United went out of their way to FedEx the ID to me, at no cost.
