Flights from Frankfurt am Main to Chicago: the best tips from KAYAK users' own experiences

Insights shared by verified travellers who flew the route from Frankfurt am Main to Chicago 
JaneFlew with LufthansaApr 2025
Connecting flights were quite a ways from each other
HeatherFlew with LufthansaAug 2024
They are super strict on carry-on size and weight. I have never seen an airline weigh a carry-on before. If you are flying through Germany, make sure to alott yourself extra time to stand in a giant line for a passport check, even though it was already checked when boarding to Germany (not sure what could have changed with it during the flight!). They had given some of our seats away on our connecting flight because we barely made it to the gate in time for departure.

Avoid Frankfurt and O'Hare if you can. Use Amsterdam as your European hub and Minneapolis or Dallas as your hub in middle America.
