Errata

I'd appreciate the help of FT'ers after struggling to find a definitive answer on the Swiss and Star Alliance sites.

I am *G and will be travelling LX Y with a friend from DXB to ZRH in a few days time. My ticket was issued some time back in March.

Firstly, I understand that I get an extra 23kg bag, making my total allowance 2 x 23kg. Will this privilege also be extended to my friend with whom I will be travelling and checking-in with?

Secondly and more importantly, I have a folding bicycle, 11kg, that I wish to take as my second piece of baggage in addition to my ~20kg case. Will I be allowed to take the bike as my second piece of baggage or will I be charged something, despite the fact that it is folded away into a size less than that of my case?

Thanks in advance for the assistance.
