Airlines recently adopted a one bag policy. You get one bag that is 50 pounds or less. Any more than that and you must pay extra. 50 bucks a bag if memory serves.
Luckily, for us, this policy was not in place when we made our last trip to Germany. I posted about my bag nightmare both here and here.
I also promised pictures which I forgot about until now. Here's our little car in Fulda Germany with all of its luggage.
