I had EMECO do a reissue for me while in Cairo back in February before I started the ticket (kept first international flight the same) and it was all done with ease. I went directly to their office from the airport and they took care of it from there. The ticket was delivered to my hotel the next day. As a funny aside, it was a cash purchase and the reissue entitled me to a refund of an extra Asia segment I had originally needed. They gave me the refund in cash minus the change fee. You can imagine how thick a wad of cash $400 worth of Egyptian Pounds is!
