> I guess the best option is, to use a good reseller/travel agency that provides an API/MCP for booking and managing flights.
But do these actually exist?
Duffel is the best one I know about. Not directly for consumers but good for platform businesses who need an API.
Not that I know of, the best work around is hitting up Google Flights, but even that doesn't make things easy.
I honestly can't believe there isn't a SF based startup that is already doing it.
The usual issue of flight booking APIs is, that those flights are expensive. It's what travel agencies or travel departments in companies use.
You have to get the data from a GDS and it looks like Sabre offers one already [1]. That said I don't know if just anyone can sign up for it.
