What's more, maybe EK was trying to be clever, routing code share flights over Iran when no JetBlue passengers were physically on board. On the surface, that seems reasonable, except the law said no seats can be 'offered for sale' on flights transiting Iranian airspace, so in arrears the US government decides to make an example of it. It's really not the big deal that the thread starter took it for, but it does show the layers of subtleties tied up in these code sharing arrangements.
