I look at this new "enhancement" and think...mheh. It's great for non-elites but as a 1K offers me very little. AA and DL offer same-day confirmed at no cost to top-tier elites regardless of fare class booked and whether or not that fare class is still available. With UA, any advanced-purchase fare class is likely zeroed out by departure day so, even though there is not a change fee, I am still socked with a fare difference if I want to confirm a different flight.

I would encourage UA to think long-term here. Biz travel will return and the day will come when that is what matters again so UA needs to be thinking about how to take care of their best customers...people who are not transactional customers.
