Very true and with a lot of passengers holding IATA BSP tickets (the "neutral documents"!) how is this info going to be publicised?
And ofcourse the magic number of 32 KG (no doubt as per Health and Safety demands!) is also certainly influenced by all these transit bags which has to be transferred to/from the various BA aircraft enroute to/from USA from other parts of the world served by BA!
I thought the Brits preferred rounded off numbers and would have preffrred a nice figure of 30 rather than the unwieldy 32! But then I suppose health of all parties (and not just health and safety blokes) have to be considered and some give and take is in ORDER!
