I have a 07:15 flight on Sunday Oct 28th departing from London Luton Airport. Owing to limited options on public transport, I will be arriving at the airport at ~00:30. Is there any chance I will be able to go through security earlier than the usual 3h and wait for my flight in duty free?
Edit: I have no checked bags - only carry-on. It is an international flight to a destination outside of the EU.
I was finally able to get into contact with London Luton Airport, who stated that i'd be able to pass through security ~5h before departure - which is the point at which the airline activates the flight.
Be aware that Luton airport is pretty grim generally; it's a permanant building site and there is very little to do before security. I had a similar transport issue and had to wait until 2 hours before my flight before I could go through. There's also a shortage of seating before security.
