Hey... so I might have a problem. Air France's Dublin to New York flight gives me one hour and twenty minutes layover at Paris CDG. However it won't let me online check-in for the second leg (Paris- New York) It says: "You or one of the members of your group can not use Internet check-in, due to a check-in restriction. Please check in at the airport". Worried that in the time it takes me to get from 2E to the check-in desk, sort out the problem, and rush back to 2E, I will miss my flight.

This is my first time to either France or the US. Are they obligated to put me on the next available flight if I miss it?
