Snow affects travel through Chicago

What is being called the largest snowstorm since 1967, is pre-emptively shutting down airports and bus terminals.

Megabus travel and airlines at both Midway and O’Hare International Airports have canceled travel for commuters for the approaching snowstorm.

At O’Hare, airlines have pre-emptively canceled 1,300 flights, and inbound and outbound flights are seeing delays of 30 minutes or more, according to the Chicago Department of Aviation. At Midway, airlines have canceled all flights for the day.

Both O’Hare and Midway will remain open even though flights are canceled, said Chicago Department of Aviation spokeswomen Karen Pride.

The Chicago Department of Aviation is advising members to check their airline’s website or call prior to leaving home. The CDA is also advising those with flights still scheduled to arrive to the airport two hours prior to their flight.

Megabus travel is also severely affected, and Megabus has canceled most routes across the midwest Tuesday, according to megabus.com.

Megabus is advising all riders to check megabus.com or call 1877-Go2-MEGA.

Amtrak has not canceled any trains and is running on-schedule , according to Amtrak spokesman Marc Magliari.
