Sorry if this has been asked, but Google Flights is showing that Vueling Optima is fully refundable, but Vueling.com suggests only TimeFlex is , and then only for credits, not for a full refund.

I'm assuming Google's just wrong, but anyone have any insights (or other tricks for refundability?). I know it's cheap but these are for flights far out so want to be protected (i'll do travel insurance anyway - this is part of a much longer trip)

Also, the prices are slightly diferent anyway, even for same flights. Again, I assume Google is just wrong, but would love insight; I've never flown them before.
