Its not just city alone either Additionaly Take a look at the ads and where they are placed around west coast airports !

Maybe noticed things like 'general purpose' ChatGPT ads in the middle of the terminal where the 'domestic travel public' goes and near Southwest gates, inference API token router style AI ads closer to the lounges and higher end airline gates.

Slightly different classes of ads around Delta One lounge in LAX, which is the highest end Delta lounge, compared to the ones next to Delta Sky Club for instance, even both are lounges

I've not travelled to too many places on the west coast except LAX and SFO [SF is my main goto] but I'll have a look the next time I'm around :)

Take your point re different classes of ads, it makes sense! I've not seen any ChatGPT ads here in Europe over the last few months - I'm travelling to London again next month so perhaps I'll see some there, I think one reason for that at least is that U.S. consumers have ever so slightly higher purchasing power and the adoption rate is still relatively low amongst the general population of the US of people who subscribe to the pro tier of any generative AI app.
