Terrible airmanship and rt procedures. And this crew with faa licences had no idea how to declare an emergency properly under icao(to which the usa has signed up to) procedures.We are all supposed to be professional and it sounds he declared his emergency for spite.The controllers acted entirely professionally in this situation and i hope the faa flight ops inspectors met this aircraft on arrival at the gate to check the fuel.If the pilot could not land due to cross winds and fuel permitting should have diverted to his alternate considering the runway works would have been published in the notams
