Does someone have the definitive answer to this scenario.
You arrive at the airport in reasonable time, i.e. before the checkin is closed + a buffer. You checkin at a desk provided by the airline in question. You then arrive at security where there is a huge delay due to either lack of staff or broken equipment. It is a major airport wth multiple departure runways, many wide-body flights and so many many pax with flights departing within the next hour. All pax are trying to get to jump the queue. You miss your flight due to Airport services. Where do you stand for compensation? Does EU261 cover only claims against the airline; what about other links in the chain.
If the EU-crats dreamed up this EU261 deal because of their own irritation at delayed flights, as alleged by someone, did they also apply it to Eurostar?
