I'd like to see minimal cabin baggage implemented - you want to see how quickly 90 North Sea bears can be loaded and unloaded from a 146 with no cabin baggage when the only thing between them and the pub is the flight. Yes it's a bit tongue in cheek, but it really does show the difference between regular pax who want minimal inconvenience and normal domestic pax who want all their creature comforts with them while extracting every penny of value for their ticket price.
As for the airports encouraging multiple bags of duty free, that's another rant altogether.
Well done to all involved, good outcome to something that could have gone horribly wrong.
