this is the address to complain to for emirates:
customer.affairs@emirates.com
please spread the e-mail around to others who need it, i think emirates' service in general is not commensurate with its reputation, considering that it has obtained awards like "airline of the year"...
they charged me for excess by counting the weight of my laptop bag, even though this is not common practice amongst airlines of their stature, and even though it is not written anywhere, on their site or on the tickets, that laptop bags are counted in the weight limit. then i complained and they basically gave some lousy excuse without addressing the heart of the issue: laptop bags are very simply not counted for excess baggage! so i replied and they basically ignored my appeals.
so please spread this e-mail address around. i have an extremely poor impression of emirates now since it has such incoherent policies and lousy customer service.
