As far as I understand, JetBlue was founded as a point-to-point airline: meaning, they didn't really do connections; most passengers were O&D, etc.

I'm not a JetBlue flyer so I don't know much about whether they sell connecting flights on one itinerary now and if so, whether that's something that changed recently or a few years ago. How much is this like Ryanair's approach, if they don't sell connections? Do JetBlue through-check luggage on separate tickets if both flights are on B6?

For some years now I understand they've had "focus cities". To what extent do those function as JetBlue "hubs"? Do people now consider them a hub and spoke airline? Do they themselves think of themselves as such?

Has this perspective changed over the years?

Interested to hear your thoughts.
