Airport Shuttle

Several ground transportation options are available for Meeting attendees. Chicago's airports—O'Hare International Airport and Midway International Airport—offer shuttle services to all official ASCO hotels.

Go Airport Express is the premier shared ride airport shuttle for Chicago’s O'Hare and Midway Airports and convention centers. They offer efficient and economical shared ride services, express luxury sedans, and limo services, as well as a complete line of charter vehicle services. Visit their ticket counters located in each of the airport’s baggage claim areas. Shuttles depart from O'Hare and Midway Airports every 10-15 minutes for Downtown Chicago Hotels.  Airport Express Service from McCormick Place to O'Hare and Midway runs every 30 minutes. 

Attendees may also purchase shuttle tickets onsite at the Go Airport Express Desk. Location and hours will be posted closer to the Meeting.

Go Airport Express is part of the Corporate Allies Conquering Cancer Program and will be donating 10% of the proceeds raised during the Annual Meeting to the Conquer Cancer Foundation of ASCO.
