So if the law is copied over, would that mean Ryanair having to compensate for a delayed/cancelled flight from STN-IBZ/PMI/FAO etc whereas Jet2 on the same routes would not? Flying to the UK, all would have to. Alternatively if we're out of the EU would the EU tell us to get stuffed with our claims to their airlines?
When the law is copied across, it will have identical outcomes. So compensation will be payable for services to/from EU27, and also to/from UK.
