This maybe apple and oranges, but my brother in law was one of the heads at United Corporate IT. With the merger, him and his team proposed designing a totally new reservation system as the current system could not handle the increase demand with the merger. UA said No, just fix the current system to work. They said this wouldn’t work and UA held firm. So he and others, who knew better left UA. Ever since then, with all the reservation outages and problems, I remember what happen to him. Don’t worry, he landed on his feet working for a new company, flying on their private jet and has 12 new patents!
