- SAA A350 and Delta One lie-flat win overnight sleep when seat map confirms refitted subfleets.
- Compare like-for-like dates on the same carrier when possible.
- Both cabins swap subfleets. A new PE seat on a 787 can beat an old angled business on a 777 — check operating aircraft, not cabin name alone.
