The biggest growth among its three airports was 7.4% at Stansted with 26.1 million passengers while Manchester airport grew by 6.5% to 27.9 milllion with long-haul connections driving much of the increase.
Meanwhile, East Midlands airport saw passenger numbers increase by 3.8% to 4.9 million.
The growth in passenger numbers drove a 10.2% jump in revenue to £818.1 million with adjusted EBITDA up by 5.6% to £358.8 million.
MAG chief executive Charlie Cornish said the group was well placed for the future as increased consumer demand combines with its spare capacity to drive further growth.
He added: “Manchester and Stansted are the two largest UK airports with significant runway capacity and our investment will allow us to meet continued demand for aviation growth both in and out of the UK.
“The government’s support for airports looking to make the best use of existing capacity provides a clear framework for growth, and it is critical that it now matches its backing for Heathrow expansion with specific and practical proposals to improve rail access and maximise the potential of airports like Manchester, Stansted and East Midlands.
“As the UK prepares to leave the EU, we are confident that the UK government and the EU recognise the importance of providing confidence to passengers and airlines, and we welcome the commitment from both sides to putting in place a framework that will enable air services to continue post Brexit.
“Looking forward, our resilient foundations, healthy financial position and attractiveness of our UK airports will ensure that the business is well-placed to respond to any challenges that may be felt by the UK economy in the future and we continue to take a positive long-term view of our prospects for growth.”
