A Ryanair attempt to make fun of British Airways on Twitter after a flight mistakenly went to Edinburgh instead of Düsseldorf has backfired. Ryanair's official Twitter account said it had a "present" for BA - a copy of Geography for Dummies. But Twitter users made a number of suggestions of books Ryanair could read, including "Customer Service for Dummies". In January Ryanair was again named the UK's least-liked short-haul airline. On Monday, a British Airways flight that was supposed to go to Germany ended up in Scotland after the wrong flight plan was used. Ryanair trolled BA in a tweet that afternoon with the suggested reading material. BA replied to the tweet saying: "No-one is perfect". But Twitter users quickly came back with book suggestions lampooning the low-cost airline, including "Employment Law for Dummies". In 2018 Ryanair was forced to cancel hundreds of flights after strike action by pilots and staff who were complaining about conditions. Many Twitter users poked fun at Ryanair over its practice of flying to airports that are some way from the supposed destination, for example, flying to Beauvais, which is more than 50 miles north of Paris, instead of a closer airport to the French capital
