I have scheduled transportation to the airport using this taxi service several times. The driver has always been at least on time, but usually early. The rate is very reasonable. The driver has been personable and professional as well.
One area of improvement though would be for the company to send text or email confirmation of a scheduled ride: The taxi companies I've used in Chicago sends text confirmation. It's important to have confirmation, especially when hiring a taxi for transportation to the airport [in the morning]; you don't have time for the taxi not arriving, and/or having to identify another mode of transportation to the airport the morning of travel, as it can result in a missed flight. Providing confirmation also increases the taxi company's ability to compete with ride-share services. I prefer taxis, and I only use ride-share services when hiring a taxi isn't a viable option.
I hope that I can continue to hire this taxi company for my future travel needs.
