Security screening opening hours and when to arrive for your flight

  • Security in T1 is now open 24 hours a day, 7 days a week 
  • Security in T2 opens at 04.00, so people flying from T2 should factor this in.
  • We advise that you allow 2 hours before a short-haul flight, and 3 hours before a long-haul flight.
  • If checking a bag, verify your airline’s check-in & bag drop desk opening times, and if possible, allow up to one hour of additional time to check in luggage.
  • You can also view check-in times by airline and by Terminal here
