The Striking Differences Between American Airlines’ New Flagship Cabin & United’s Polaris Business Class

American Airlines and United Airlines spent the past two years building the most expensive business class cabins either carrier has ever flown, marketing them as distinct flagship products, and placing them head-to-head on the same transatlantic routes. Both selected the same seat from the same manufacturer to do it. The Adient Elevate Ascent sits at the center of American's Flagship Suite and United's Polaris Studio, which means the differences passengers notice are not differences in hardware at all.
