Booked OSL-FRA-DFW in C on a Monday morning at 6:05 am. Arriving by train at 5:02 am (check-in does not open until 5am anyway), so things can get tight. Will check-in online of course, but will have luggage to check. Can the baggage be checked at a kiosk or will I be required to queue for the baggage drop?

LH website seems to indicate only German airports accept kiosk baggage check-in, and baggage is to be dropped at the "Drop-off counter (SAS)" at Oslo. Sometimes this information is out of date, and wondered if anyone can provide any real world experience.
