"Generally, I think Delta has made good improvements: better uniforms, investment in leather seats, a decent mileage program, and certainly a broad set of destinations all under one carrier. One significant disappointment is that it is possible to be a Platinum who books within a day or two of a flight and pays top $ and is still seated in the last row in a middle seat with no opportunity at a window or aisle. On NWA, even if only middle seats remained, a savvy frequent flyer would know to check in at the 24 hour mark and have a chance at getting a great seat. That is no longer possible with Delta as they do not reserve any seats. Well, their answer is that they do, but under control only of the gate agents. That would be great, except I don't get to a flight 3 hours in advance to ask the gate agent to give me a seat. I always show up near boarding time as I, like many others, am a busy guy. Delta: please bring back choice seating or reserve a few good seats until 24 hours before. Please. "
