Duplicate Content - International Sites - AirBNB

[joogla]

Good morning

Just a quick question.  Why does AirBNB not get penalised for duplicate content on its sites.

For example, the following two urls (and probably more for other countries), both rank appropriately in the google (UK and COM),

https://www.airbnb.co.uk/help/getting-started/how-to-travel
https://www.airbnb.com/help/getting-started/how-to-travel

Their are no canonical tags, no Alternative etc

If I look at the following

https://www.airbnb.co.uk/s/London--United-Kingdom
https://www.airbnb.com/s/London--United-Kingdom

They both have alternative to point to the other language versions which I would expect. However they also both point to them selves as canonical.  Would this not be duplicate content ?

Thanks for your insights

The simple answer is they're using a generic TLD(gTLD) and then a county TLD(ccTLD). Google has long said that it recognizes that the same content on different ccTLDs will not count as duplicate because they understand it's geotargeted
