I think United has done a great job with the integration all things considered. The lines were much longer traveling back from ASE yesterday than normal. United had way overstaffed the station. They have moved multiple CO employees to ASE for 3-4 months each to ensure the transition went smoothly. My account is slowly getting fixed.
Is it frustrating things take longer with Shares than they used to be? Sure, but it will improve with time as employees become more confident. I was Chairmen's for a number of years with US. That was a horrible integration. People could not fly for days. I am focusing on how much easier things will be with one system. I will no longer have to worry about flying on mixed-metal trips and the implications. It will get better with time and I appreciate how hard the line employees at United are working.
