This might be useful for some - According to the article if you end up travelling on a BA booking but actually flying with Vueling on a codeshare, you can’t register any potential EC261 claim with Vueling utilising your BA booking reference you need the PNR on your boarding pass. Wasn’t sure to post here or on the media thread or if at all ! So please feel free to move or delete !
I will slightly expand on this: EC261 always applies to operating airlines, so whether codeshare or prime. Only occasionally will BA be responsible for services operated by other airlines. The main Vueling claim mechanism is a "chatbot" (it's not really, it's just an online form) and that form asks for the the VY PNR, the BA PNR isn't good enough. You can find the Vueling PNR on the boarding pass or via the Vueling App by first entering the BA PNR - it auto translates. You can also claim EC261 from Vueling by ringing them up (0203 514 3971, office hours) or via Twitter Direct Message.
