As Swissflyer says, this is just about money for IATA and the bag makers. Customers can just f.o.
What he said.
It's just not realistic to continue stories about IATA making money on this to enrich themselves.
Lets see, I'm guessing its going to go down the normal commercial route of ...
IATA getting a trademark on the "IATA OK BAG" logo.
IATA licensing said logo to manufacturers
IATA receiving an upfront payment and/or ongoing royalties for said license
In the end it's up to voluntary compliance with this suggestion so voice your objections by choosing your carrier as you do today.
Maybe, but frankly what carrier is going to vote for Christmas ? They're all going to fall into line like dominos.... the smaller sizes enable them to cram in more SLF, the "IATA OK" logo means they don't need to have bag sizes and cages any more .... they just need to introduce a "Anything without an IATA OK is strictly verboten" rule in their conditions of carriage.
Personally, I find it quite ironic that the IATA mission statement says :
Advocating for the interests of airlines across the globe, we challenge unreasonable rules and charges
One rule for them and one rule for us eh ...
I see the IATA has a regional office in Florida, are you sure you don't work there lomapaseo ?
