I see that my checked in allowance in J is 30kgs and my cabin baggage allowance is 10kgs. According to the website I can use part of my cabin allowance in the form of a suiter which would work really well for us as we are away for 4 weeks and include a cruise and a wedding however, how does this work at airports such as going through Heathrow flight connections who will not allow me to carry more than one item of cabin baggage? I had hoped to use one of our 10kg hand allowances as a suited, and split mine as a suit bag and small backpack for pc books inflight items etc.

Also how strict are they at Sydney on the return trip re weight at check in - I am relatively happy I can charm the BA lady I will be checking in with in Edinburgh on the outbound journey

Thanks
