Today I read that the US has decided to stop transits through the US without visas (for many countries' nationals), which will impact on US airlines, despite no proof of a real risk from such people. It takes months sometimes to get a US visa, even crew visas are now subject to Interview, which puts a month onto every application.
And they have decided to "crack down" on computers, digital cameras and the like in hand carried bags, again despite no demonstration of a risk, which will make airport security even more of a hassle with no safety or security gain.
Johny Howhigh will no doubt follow the lead of his mate George.
