Expanded Preferred Seats in Coach
Taking a quick look at some of my itineraries, but I'm noticing a lot more preferred seats on the seat map for upcoming flights.
Some flights don't see anything changing, but other flights (primarily ones at heavy business travel times on busy routes) have several (in one case, I think 20 rows or so!) blocked for only elites/full Y fares to select.
This is a huge step up from only having the first two non-bulkhead rows of coach (plus exit rows) being reserved for elites.
A major improvement for elites out there that book late and now have a much better chance of getting a window/aisle seat instead of getting a middle! Nice work Delta!
