I'm traveling out of Chicago to Rome with Swiss International in July and have a 1 hour and 40 minute layover in Zurich. On the way back we're flying out of Paris to Chicago with a 1 hour and 35 minute layover in Zurich. I'm wondering if the layover time in Zurich is going to be enough? I'm really worried we aren't going to be able to make our flight to Rome and back to Chicago! Thanks for any help!
