I flew F PHX-SEA-PHX last week. On the way, we had the Meatball entree. It came with a small green salad and a packaged stale-tasting cookie. It was pretty good -- the meatballs were tasty. On the return flight, it either a garden salad or rock shrimp and lobster ravioli. I had the ravioli, but it was frankly awful and tasteless with the same stale packaged cookie.
I honestly hadn't flown Delta F in years, but found the meal a bit lacking when compared to AA on the same route. AS has downgraded their service in F to sandwich/chips/better or protein plate, but I would have preferred either of those to what DL served on the return flight.
