Ignoring the stench of racism in your comments:
*Then why did the US and UK pick different countries?
*Why is this only for certain airlines, and not for all airlines in that airport?
*Why is it only for certain airports, and not all airports in a given country (only one of two international airports in Morocco were mentioned. Its not that hard to get from Casablanca to Rabat).
Or we can take the obvious answer- its all bullshit, and you're a racist prick.
