Airline rewards programs
Winner for elite status and rewards: Alaska
Atmos Rewards (Alaska)
Alaska undoubtedly has one of the best remaining loyalty programs in the United States. Especially with its acquisition of Hawaiian Airlines and membership in the Oneworld alliance, it maintains its status as heavily lucrative and generous to its members.
The Alaska-Hawaiian joint loyalty program is called Atmos Rewards. There's a semi-dynamic award chart and there are some excellent redemptions to be found in economy and business classes on Alaska, Hawaiian and their airline partners. Because of this and among other reasons, NerdWallet values Atmos points at 1.2 cents each.
The Atmos loyalty program is also generous, with great mileage earnings and other benefits for its members.

Delta SkyMiles
While there are still Delta SkyMiles loyalists, the airline chipped away at its program in recent years to limit benefits to only its highest spenders. The requirements to reach elite status are very expensive, with the lowest level starting at earning $5,000 Medallion Qualifying Dollars.
On top of that, redeeming SkyMiles for a good value has become increasingly difficult. NerdWallet values SkyMiles at 1.2 cents each.
In-flight experience
Winner of the sky: Delta
Alaska
Alaska operates fewer flights than Delta and a much smaller route network, especially when it comes to long-haul flights. Because of this, it only operates cabins in economy, economy plus and first class. The first class seats that you’ll find will recline but don’t turn into beds; they resemble large recliners more than anything else.
Those in first class are entitled to complimentary meals and alcoholic beverages, and those who are flying in economy plus also receive free alcohol. Anyone seated in economy will get nonalcoholic drinks and snacks.

Delta
Delta maintains several cabin classes, including economy, economy plus, premium economy, business and first class. The type of seat you’ll get will depend on where you’re flying.
Premium economy is akin to domestic first class as you’ll find on both Delta and Alaska, with large reclining seats. Those in Delta One, the airline’s premium business class product, will enjoy a lie-flat seat, high-end meals and complimentary alcohol.
Those traveling in economy will receive free snacks and nonalcoholic beverages, though on long-haul flights meals and alcohol are included.
