Scotland's airports recorded mixed results in relation to the number of people passing through the terminals last month.
Bosses at Edinburgh and Aberdeen airports said a shorter February this year contributed to a dip in passenger numbers when compared with the same month during the 2012 leap year.
A total of 563,900 people travelled through Edinburgh airport, a drop of 7.8% compared to the previous year, taking into account the extra day. Comparing like-for-like passengers for both years, the airport saw a drop of 4.7%.
Gordon Dewar, the airport's chief executive, said: "Despite this reduction, last month's passenger figures hide good performances from a number of airlines, all of which saw traffic increases.
"We have worked hard to overcome the challenges we faced in 2012 and have secured new destinations for our passengers. Both Ryanair and easyJet are launching six new routes in the coming weeks.
"April will also see the launch of Little Red, the new Virgin Atlantic service from Edinburgh to London Heathrow. This is hugely exciting and will help redress the shortfall of domestic services impacted by the extra day in February last year."
Aberdeen airport said a reduction in the number of helicopter flights was also a factor leading to a drop in the traffic figures.
The number of people passing through the airport was down 1.2%. There was a rise of 1.7% recorded in the passenger numbers for aeroplanes but a 15.1% decline in helicopter numbers affected the overall traffic figures.
Meanwhile, Glasgow airport welcomed more than 423,000 people, a rise of 2.1% after adjusting for the leap year. Demand for travel to London was credited with driving growth while international traffic was in line with 2012.
Amanda McMillan, managing director of Glasgow airport, said: "It is encouraging that our passenger numbers showed modest growth in February, which was largely due to the strength of our domestic services."
