The CO 752s have the same. And my understanding is that the new UA system is comparable, though Y pax have to buy the additional content. The company is deploying the new system across all long-haul aircraft. Sure, it takes some time to do so. Probably longer than any of us would want, though it isn't wholly unreasonable that they cannot just do it all overnight or even in a month.

Still, the claims that COUA are so far behind are, at best, only partially true. The one specific claim comparing to KLM is so full of misleading information that it is ridiculous.
