That is a very reasonable suggestion
lepidus but I feel some of my lists coming on. (regulars know I like lists ...)
Unfortunately, you would need to gain the 100% agreement to both implement and enforce this from:
- Every major and medium sized airline in the world. A quick tally says that's about 75+
- Every national Aviation Authority in the world.
- Airbus, Boeing, Bombardier, Embraer, Tupoloev as the majors
- Commercial Aircraft Corporation of China, Ltd. and Mitsubishi as the new boys on the block.
- All luggage manufacturers to change their ranges, tooling etc.
Since:
- 99% of these want to offer something 'different' to their competitors ...
- A majority (my opinion) of carriers don't like implementing the luggage rules they already say that they implement ...
I fear that it's not going to happen. As I've said before, changing these rules will only happen when:
- Enough pax have died
- AND It can be proved that their deaths were the fault of luggage
- FURTHER that 'innocent' pax died because others were taking hand luggage out with them and blocked both themselves AND the following pax.
