US Citizen Flying Swiss Air LAX to Charles De Gaulle but laying over in Zurich. We are planning on remaining in Zurich and not continuing to CDG. If we check our bags, will we have to retrieve them anyway before passport control in Zurich, then re-check, so we can do so and just leave? Or are the bags checked through to CDG. Can't seem to get a for sure answer from United who we booked through or Swiss Air. We will carry on otherwise but are traveling with two toddlers so would prefer to check.
