One runway, one terminal, and somehow still room for a temple complex older than Stonehenge. January fares dip to $55, which tells you everything about how the crowds behave the rest of the year. Rome is 1h 30m away for $65, London 3h 05m for $85, so the maths favours the impulsive as much as the planned. Just don't be the non-Schengen passport holder stuck in a 30-40 minute August queue wondering why you didn't book those instalments back in spring.
