DB "Europa-spezial" tickets and local connections
I have a €39 "Europa-spezial" ticket from Paris to Frankfurt Airport (S-bahn station) via Frankfurt main station.
The train from Paris to Frankfurt Hbf is on day 1 and the connection to the airport is on day 2. Specific trains are identified on the ticket for both legs with a reservation on the main leg but obviously not on the the local S-bahn Frankfurt to Frankfurt airport leg.
I understand that my ticket is only valid for the Paris to Frankfurt stretch on the specific booked train. But what about the local connection to the airport? Can I take any S-bahn train on the day or am I limited to the specific local train mentioned on my ticket?
FWIW, ticket says that it is only valid on booked trains ("gilt nur in gebuchten zügen")
