I am in the TXL AF lounge (open 4:45 AM).

I used SP but the AF agent did not want to interline my luggage. He seemed not to know how to do this. I told him twice AF had an interline agreement with DL. I was prepared to point out I would miss my connection at CDG if he did not interline my luggage.

Eventually the AF agent got the tag correct but I wondered for a moment if I would have been lost without my paper ticket and if I should have printed out DL’s interline agreement with AF.
