I'm supposed to be flying from London to Dublin on Thursday and have a British passport that expires in 4.5 months. When I booked my flight 2 months ago I checked the rules and it said that due to the common travel area British nationals don't need a passport but should carry it anyway for ID (www.gov.uk/foreign-travel-advice/ireland/entry-requirements). It never occurred to me to check with Ryanair whether they would allow this (my bad) and today when I went to check-in online it said that I need 6 months on my passport. Has anyone else had experience with this and do you know whether I will be allowed to travel? I can't speak to customer services until tomorrow.
