i'm leaving jan. 15 (flying northwest airlines) and will be in berlin for two weeks. does anyone have advice for best ways to have a bike with me? i'm considering packing it up in a bike box and taking it on the train, but i've heard some horror stories about bikes getting super destroyed doing this.. i'm also not sure if there's an additional fee from the airline. advice?? rent a bike there? buy a proper bicycle luggage carrier? i'm thinking if i take a bike i'll take my track bike so as to make reassembly easier and to bump up my prospects of finding my bike in fair condition upon arrival. what do you think? any help is appreciated.
