If you have trouble call 847-673-1000. You can call this number for immediate pickup or to schedule ahead of time. It's best to schedule ahead of time to ensure that we have plenty of cabs at the airport. Once you have landed and received your luggage in the baggage claim area, you will either respond to the automated text message that you will receive upon arrival with "R" for ready (these instructions will be in the text message you receive). Or you can call that same number to notify us that you are ready for your car. You will then receive your car number with instructions on where to meet the driver
Other options, Uber, Lyft and other taxi services
If you have any other services you recomend let me know and i will add them to the list.
