I've been waiting in lines for hours. Then i get in another line that does the exact same thing as the last line i was in. Who is in charge here? This set up makes no sense.
Do u have just 40 min for transfer between flight? Do you hope that Etihad staff will meet u at the plane and guide u as Lufthansa does? No they don't.
Worst airport/terminal (3) to be in transit. Coffee is shit, and coffee shops here have no tables and no outlets. Beware that they don't allow liquid onboard even if u bought it here!
One of the worst airports I have been to. A lot of walking, badly organised, full of constructions work, very slow WiFi. Avoid this airport and avoid using Etihad airways!
