It looks like someone really liked wood slat room dividers [1]. Or maybe a lobbyist for the wood industry was involved.
Wood slat partitions were seen in mid-century modern designs, when rooms became more open plan but some sense of division was needed. They were also used in the 1970s to make small cheap apartments look bigger.
Still, it's good to see some US airports looking better. Most of the Asian countries have much nicer airports than the US.
