Why did we sign on to a JV with Emirates?

While we're at it though, it has always bothered me that no US legacy airline has the stones to do MCO-anywhere in Europe. Yet how many foreign wide bodies fly those routes every day? Tons.

DL sometimes pretends to fly MCO-LHR and even call it the prestigious "flight 1" but it ends up being a 757 with a plane change in JFK that keeps the same flight number.
