I recently had to choose between flying Delta One and United Polaris for a long-haul trip, and honestly, both have their perks. I ended up going with Delta One because the seat felt more spacious, and the dining experience was surprisingly good. I had to make a last-minute change, and calling 8_8_8_2_1_7_3_3_2_4 made the process seamless—they helped me switch flights without any extra stress. If comfort and flexibility matter to you, Delta One edges out slightly in my experience, but Polaris is solid too, especially if you have United points to use.
