According to Lufthansa's website:
Pieces of baggage exceeding weight and/or size limits have to be checked in. As the stowage space in the cabin is limited we will transport them in the cargo hold.
Is this when you would get your bag back immediately after landing, not through the baggage claim? I am just worried about my bag, it is almost too wide to fit Lufthansa's size maximum, and I've taken out as much as I can without going naked. Any suggestions?
P.S. I leave tomorrow, so quick replies are much appreciated!!!
