Weight problems

So here is the summary of airline/sealine excess baggage charges (say that while deepthroating salami at the Waitrose meat counter, at the same time, whistling the theme tune to 'The Archers'):

• Air China LHR - PEK (£400, but waived thanks to both judicious flirting and more likely, blind luck)
• China Eastern PEK - PVG (a few hundred Renminbi, paid)
• China Eastern PVG - SZX (not bothered/waived)
• Ferry Shekou - HK (a couple of hundred Renminbi, paid)
• Cathay Pacific HK - TPE (a couple of hundred $HK, paid)

But it's the final leg that concerns me, back to Blighty.
