I want to fly DFW-FRA-GOA returning MXP-JFK-DFW (overwater segments are in Premium Economy) for a cruise from GOA
<snip>.
So, the issue is whether we will need to pick up bags at FRA, extending our exit from the airport, and possible LH bag fees if we need to recheck
You will need to clear immigration at FRA after your DFW-FRA flight. And probably customs (baggage) as well. Or maybe customs in GOA. Others know a lot more about Eu immigration & customs procedures & checking in for LH flights.
