First of all, let me second the comment that was made about how poor the coach product really is. I'm a Delta GM and I've been flying more on AA lately (where I have AA Gold level as a holdover from my TWA days) and I really appreicate the extra leg room and more importantly the power plugs for my laptop. The only DL flights that that good are the Shuttles.

Secondly, what DL has finally done, with this change in addition to the changes in the last few years, is to completely eliminate confirmable (at time of booking) upgrades for anything but an M-class fare. These fares are too expensive for my corporate travel policy, so this means that when I fly DL I'm now in limbo.

Why shouldn't I just switch to flying AA? If I reach AA Platinum I would have the same segment upgrade benefits as on the new DL, but I would also have more comfortable seats, power adapters in coach if I don't get an upgrade and, more importantly for me, the ability to confirm an upgrade on a discounted far at booking, using my miles. Granted, I have to spend more miles for the upgrade, but I feel it is still a better deal to sit in the business cabin on a 6-hour flight.

So, Bruce and your team at DL, why shouldn't I and others like me switch to AA?
