An Bord Pleanala has given the green light for a new runway and terminal at Dublin Airport.
Phase 1 of the new terminal was passed, subject to 30 conditions, however a proposed further expansion was refused.
This means the new terminal's floor space will be kept at 75,000 square metres, rather than 92,000, as had been proposed under a phase two development.
On the runway, the Bord granted permission, subject to 31 conditions, and there-by opted not to accept its own inspector's recommendation for refusal.
Condition 3 of the planning stipulates the new runway cannot be used for night-time flights between eleven at night and seven at the morning.
Condition 5 stipulates that night-time flights from the airport cannot exceed on average 65 between the same hours.
On the question of noise, the developers must also come to a voluntary arrangement with schools and houses in the vicinity to provide insulation free of charge.
Both developments are dependent on metro north being provided.
Ryanair confirmed that it will challenge An Bord Pleanala's decision.
It claimed that the aviation regulator (CAR) has confirmed the DAA's plan for T2 is oversized, its costs are excessive (having increased fourfold - from €170m to over €800m) and will lead to a doubling of the already high passenger charges.
