It's not really surprising and for an expected reason. It's the same reason American airports aren't all that impressive compared to other ones internationally.

It's not really surprising and for an expected reason. It's the same reason American airports aren't all that impressive compared to other ones internationally. It's because commercial flying in the US has existed for over 100 years - it is not elite anymore. Flights are relatively affordable for regular people and it is not a luxury. Many of these other airlines are newer and serve a smaller amount of their population. They are still seen as luxury. The other side of this high-quality coin is that they are not accessible the same way north American flights are to north American customers. Just like the first Tesla was a roadster for the rich that was used to start a company and fund expansion and cheapness, these airlines have started at the top-end for profit and expansion. But they do not serve everyone. Airlines in the US used to be very classy. It became more profitable to serve broader, cheaper service. What this means really is that unless the airlines are outliers for their particular region, they're actually representative of a gap that still has a ways to close.
