I know I'm stating the obvious here but still, they do it because they can.
This should also be a reminder to those thinking that EK will have problems recruiting enough bodies with a pulse to fill those seats in the pointy end of the tube - EK have no concerns whatsoever that they will get enough "pilots" through the doors.... I guess too many South American, Indian and Italian (Alitalia) and RYR pilots looking for a job, or a better paid one, for this to become an issue for EK.
