Purely market segmentation

And probably charging frequent travelers more because they can afford to pay.

I wondered if it’s to get around variable rational pricing - stop you buying it in X country that has cheaper pricing.

Dynamic pricing based on what your next best alternative is.

Like in the US they need permission to operate. If china builds a competitor i doubt they would be allowed to operate in the US
