Thanks everyone for the responses.
I am US based. Could anyone point me in the right direction regarding the small claims process?
On a related note, I will never fly Vueling again. Our flight displayed as "on time" up until the time to board at which point it updated to 3 hours late and we were informed our flight hadn't even left it's origin yet... Annoyed me enough that I'm willing to go through whatever headache to claim the €250.
