If doing the connection on two flights on Star Alliance, you are either SQ/NH or NH/NH. Neither will be an issue for checked luggage. And NH will also issue both boarding passes in Singapore.
If you do Oneworld and two flights only, it would necessarily be JL/JL which would also be smooth sailing.
Thanks a lot! Apologies for the missing info, HND-LHR is on NH and my options for the feeder flight are either SQ (SIN-HND), TG (BKK-HND) or NH.
You write that it would not be an issue for checked luggage - is it guaranteed that I could check luggage through if both airlines are part of Star Alliance?
