I can hardly see Egyptair as a worthy addition to any alliance... Remember that VOLUNTARY plunge from the sky by a MS 767 in 1999 or 2000 off Long Island ? It is now viewed by many as a rehearsal or planned training part of the 9/11 attacks.

ET is a different story as one of only 2 successful African airlines (with SAA), and a 85 % + ratio of intra-African pax not going through ADD or, on the contrary, connecting there. It really is "ET Avoid Home"..., which I fully understand having been there way too often.
