Passenger numbers at Scotland's biggest airports soared last year, according to new figures.

More than 10 million people travelled through Edinburgh Airport in 2014, a 4% rise on the numbers for the previous year.

The airport attributed the growth to an 89.6% increase in long-haul traffic after the introduction of new services to destinations such as Doha, Chicago and Philadelphia.

Domestic traffic from the terminal was also up 3% on 2013 with new and increased services to London airports.

December's passenger numbers at the airport rose by 7.2% with a total of 691,922 people travelling.

Gordon Dewar, chief executive of Edinburgh Airport, said: "Last year we achieved what we set out to do - to offer our passengers choice, a great experience and to cement Edinburgh Airport as the place where Scotland meets the world.

"We welcomed new airlines and retail partners and opened our brand new terminal extension and security hall, all with the passenger firmly at the centre of our operations.

"We want to harness the successes of the last year and use this to drive our performance over the next 12 months.

"For us, that means more routes, more investment in our services and welcoming more passengers."

Glasgow Airport recorded its busiest 12 months since 2008 with more than 7.7 million passengers passing through its doors, up 4.8%.

The airport secured 20 new routes and services during the year, including the Ryanair airline which it expects to generate an extra 850,000 passengers each year.

Domestic and international traffic increased by 2.6% and 6.9% respectively in the airport's fourth consecutive year of growth.

Almost 520,000 passengers travelled through the airport during December, an increase of 13.5%.

Managing director Amanda McMillan said: "2014 was a remarkable year for Glasgow Airport and our performance exceeded all expectations.

"We have now recorded four consecutive years of growth and have succeeded in attracting 1.2 million additional passengers since 2010.

"The final quarter of 2014 was particularly strong and we start the New Year in an excellent position.

"Having succeeded in securing 20 new routes and services in 2014, we fully expect to move back above eight million passengers this year.

"With events such as the Turner Prize, the World Gymnastics Championships and the European Judo Championships already confirmed, 2015 promises to be yet another special year for Glasgow."

Aberdeen International Airport had the busiest year in its history, with more than 3.76 million passengers passing through the terminal.

The figure is an 8% rise on the 3.48 million recorded in 2013.

The airport also experienced a 6.8% year-on-year increase in December to 283,136 due to growth in fixed-wing and helicopter operations.

Managing director Carol Benzie said: "It's a great achievement to see us reach such a high passenger figure and set what is a new record for us.

"The year ahead will bring a number of challenges, but along with these, plenty of exciting developments.

"First and foremost, we look forward to working with our new owners in continuing to develop the airport and our offer to passengers.

"We will continue to work closely with airlines to improve connectivity to and from Aberdeen, and challenge relevant authorities on key issues including the devolution of Air Passenger Duty and surface access to our airport".
