I am off to Dublin tomorrow, at midday from Heathrow, and have just noticed on the aer lingus website that for flights within Europe, it is suggested that passengers get there 2 and a half hours before the departure time. In my poor befuddled head I thought I only had to rock up an hour in advance! I booked a midday slot because I thought I could get up at a normal time, bearing in mind I'll prbs need an hour and a half to get to the airport. What kind of gap does everyone else leave before domestic flights?
