I spent over $2,000 to fly United Polaris, a 'reimagined' business class. It's only worth it for trips over 10 hours.
Briefly

My experience on United Polaris was exceptional, from the lie-flat seats and high-quality bedding to the rich entertainment options—it made long-haul travel truly comfortable.
Despite facing a flight delay, the luxurious seating and top-notch service with everything from a noise-canceling headset to a stylish amenity kit made the wait worthwhile.
While the United Polaris has many luxurious features, my preference is still to upgrade only for flights lasting 10 hours or more, to get the full value.
The introduction of United Polaris not only transformed their business class experience with innovative design elements but also ensured a significantly relaxing travel environment.
