It is not about specific routes. Obviously there are many US/Canada -Europe direct routes that will not be of interest to the big 3. Ditto Europe-S. America. And US/Canada-Far East. Those are clear to anyone with a brain. And Europe to Far East trunk routes will stay clear for those few that don't want 3-4 hours in the terminals of Dubai, Abu Dhabi, or Qatar, and can pay for it. . Business travel. But N.America/Europe economy/premium economy travel to ME and Far East will be taken by the sheikhs like never before. Which is a large proportion of international travel, esp from the UK and Europe. That is where our weakened airlines will no longer be free to compete.
Boneheads please stop picking routes that won't be of interest to the ME 3. They are obvious.
