Is current health and safety guidelines not 32kg then? BA have always been more generous for economy pax with a 23kg limit, but what if you've paid for a club or first ticket? What if you're flying to the US where according to IATA allowances are 2pieces at 32kg? (Although a lot of the US airlines are now ignoring this!)
Flying is getting more confusing by the chopping and changing of things like this it is more hassle for the average pax to understand easily.
