Thanks for explaining this to me! So if I understand you and MichielR correctly, they might opt for a standard seat, which Hainan already uses in their existing A/C. Iīve just looked that up and I think the seats look great compared to the current (outdated) product of LH. How much customization would you say will be done to the seats before they are ready to be installed into the LH A/C? I guess they will not go with the colourway that Hainan uses.
Additionally, from a passenger point of view, I donīt find it very conveniently, that they introduce a different seat featured only in 5 A/C as this might lead to some confusion regarding the choice of seat. On the other hand though, the afforbalde price of those A/C might be worth it, anyway.
