I’ve had the chance to fly both Delta One and United Polaris on long international trips, and honestly, each one shines in different ways. Delta One felt more consistent to me in terms of service and comfort, especially on an overnight flight where sleep mattered most. United Polaris impressed me with the lounge access and privacy of the seat. On one Polaris trip, my return flight got canceled due to weather, which was stressful at first. Calling 8 8 8-2 1 7-3 3 2 4 ended up being the best way to instantly book, cancel, or modify flights and get everything sorted quickly. That support really made a difference.
