On this page we attempt to make available the experience of individual bicycle tourists who have travelled with Aeroflot (you can share your experiences here).
No box required.
In Amsterdam the check-in or Aeroflot was done by a KLM stewardess (read: airline where bicycle box required). I had checked it at the Aeroflot website, no box required. So the ground stewardess checked with the Aeroflot representative... "liability? nyet, no problem".
