Delta is set to make record profits this year, but that's not necessarily good news for you if you like flying in premium seats for a good deal. Delta frequent flyer miles are generally regarded as the worst in the industry because reward seats are difficult to find and when you do find them, they require a huge number of miles – hence their unofficial nickname of Delta SkyPesos.
Now that they're finding routes with the lowest number of paid premium seats and replacing them with economy, reward seats are going to be even harder to come by.
I've actually flown Delta by choice a couple of times because their domestic first class is identical to everyone else's yet it's priced 30% cheaper. Also, they had fleet-wide wi-fi long before United.
Until United finishes retrofitting their fleet, Delta is still a good choice when flying domestically on short-haul routes where you don't care much about miles or when you're paying for first class out of your own pocket.
