Buffy couldn't help but overhear it all. Mostly because she was deliberately trying to overhear it all. Mind you, her way of following them... Good thing it was a busy airport, 'cause she would so be spotted anywhere else. Add to the mix of people hiding her visually, she was aware it was likely also hiding her scent.

Still gross, the whole scenting people thing.

Okay, so there two were looking to protect... someone? Something? A group of people? Either way, it was a protection deal and now they were going out to Vegas.

She did not have money for a last minute ticket on their plane to Vegas, and she was not doing the hide in the luggage compartment thing. ... She'll continue to tail them as long as she can. See if she can get any hints of where to go in NY.
