If we book these flights on one ticket, which I would prefer to do in case of delays with the first flight, when we check in at LYS can we ask to have our bag only checked through to LHR and not OSL? If so we could then collect our bag on arrival at LHR, pick up the other bag from luggage storage and then check in both bags to OSL. I think that would be easier than having one bag checked through to OSL from LYS and then try to check in the extra bag at LHR for OSL.
Thanks for any advice you can offer.
check your bag through from lys to osl, then at heathrow collect the additional bag and check it to osl
