What car service?
 

Coming to Chicago 3 adults (2 grandparents) and a 9 year old, all 4 will have luggage. Any suggestions on a car service to use?

Which airport (Midway or O'Hare)?
Check to see if Uber picks up at your airport.

I assume you are trying to save money, is that correct?

My company uses A-1 car service, but be sure to talk to them about all your luggage. They've always been dependable.

Uber picks up at both airports, but not sure I'd trust them for anything other than inter-city travel. I'd rather use a licensed SUV cab from the taxi stand, if I weren't using a car service.

Have a good time in Chicago!

I'm at ORD and I want safe, reliable at a reasonable price.

Thanks we love coming to Chicago!
