Say what you will about the evil mouse empire, but they do a few things better than really anyone else, and with a huge, diverse client base.
One of those things is lines. I would rather be in line at Disneyworld than anywhere else, and I can't count the number of times I've been in a UA line and wished they were managed as well as Disney's. (The Disneyland->LAX T7 contrast is particularly shocking.)
Another of those things is unfailingly helpful, efficient customer service, with high-turnover, short-time cheap employees. Career CS should be able to do at least as well, but somehow that never seems to work; there must be something Disney knows, and I sure wouldn't mind if UA tried to learn some of it. If it's an incentive junket to inspire the CSRs, all the better.
Yet another thing Disney does well is have costumed characters and ompah bands appear seemingly out of nowhere from secret entrances to make walking around their parks seem more festive and enjoyable. Maybe if UA could learn some of that, and use some of those mysterious doors at ORD. That, now that, would really enhance the flying experience.
