The Southwest "Premier" card provides 1,500 points toward status, and the lowest status level on Southwest requires 35,000 points.
The former US Airways "Premier World" card would convert 10,000 of the (non-qualifying) miles it earned into qualifying miles, once per year, when you hit a total of $25,000 spent on the card in the year. The lowest status tier required 25,000 qualifying miles.
The current American Airlines "Aviator Silver" card, which is what the US Airways card rebranded as in the merger, will convert 5,000 miles to qualifying miles when you hit $20,000 spent, and another 5,000 miles when you hit $40,000. The lowest status tier requires 25,000 qualifying miles.
The Delta "Reserve" card will convert 15,000 miles to qualifying at $30,000 spent, and another 15,000 miles at $60,000 spent. The lowest status tier requires 25,000 qualifying miles.
The only other non-flying method of earning qualifying miles that I've seen in this decade was an occasional promotion US Airways would run, offering 5,000 qualifying miles for buying or renewing a lounge membership. It was not offered last year, and probably will not be offered this year.
Note that airlines will occasionally allow you to buy your way up to the next status tier if you're within a certain range, but that typically doesn't actually deposit miles into your account: you just pay the fee, get the higher status, and that's that. Last year, American Airlines offered a flat-rate buy-up if you were within 15,000 miles or 15 segments of the next tier, for example, so at 85,000 qualifying miles you could have paid a couple thousand dollars to buy up to Executive Platinum status.
