Most important tips

Know before you go

A compact traveler cheat sheet for timing, terminals, food, and disruption checks.

Transport

Use the Blue Line if downtown traffic is red

It is not fancy, but it is dependable.

For Loop hotels, CTA can beat rideshare during rush hour and major event traffic.

Layover

Build weather slack into winter connections

Small delays can cascade across banked hub schedules.

If you can choose, avoid the last connection of the day during heavy snow or thunderstorm forecasts.

Navigation

Do not underestimate terminal walking time

The airport is logical but large.

Check gate letters before grabbing food; a concourse change can turn a comfortable layover tight.

Security

PreCheck matters most on Monday mornings

Business travel peaks can make standard security uneven.

If you do not have PreCheck, arrive early on Monday and Thursday hub departure banks.
