Flights from Rome to Chicago: the best tips from KAYAK users' own experiences

Insights shared by verified travelers who flew the route from Rome to Chicago 
GinaFlew with ITA Airways-Jul 2026
We had to take a bus to the plane and get on from the tarmack. Just leave enough time to get through that process too.
ElizabethFlew with Iberia-May 2025
Get to Rome airport a bit early. The lines for passport control can be long if you have a US passport. The signage can be confusing, but once you figure it out it is easy. Staff at Rome airport are very good and the lines were not bad there. Just security and passport control.
