Definitely. Domestic is generally meh. UA Polaris has stepped up their game for sure. Bedding is A+, lie flats in 1-2-1 are better than LH (which is still 2-2-2 or 2-3-2, though if you're stuck on a 2-4-2 772, I'd take the LH flight), and the Polaris lounges offer premium alcohol and decent food. Inflight food and beverages (same liquor as the rest of the plane) aren't as good, and service is still a joke compared to any non-US carrier though.
