Chicago O'Hare Travel

More than 500 passengers were stranded at Chicago O'Hare's International 
Airport last night. Flights have been canceled or delayed in most of the 
Midwest, and highway travel is hindered by snow and ice storms.

The stranded travelers had to spend the night at Chicago's O'Hare 
International, said Chicago Aviation Department spokeswoman Karen Pride.

More snow fell Wednesday in the Midwest, where the National Weather Service 
said up to 4 inches was possible in Chicago.
