BAA airports saw a 4% rise in passenger numbers in March compared with 2011, although this was largely due to the fact that Easter fell earlier this year.
BAA said there was a 6.9% increase in traffic at Heathrow, which handled 5.7m passengers in March, pushing its total for a 12-month period to over 70m passenger for the first time.
BAA-owned Aberdeen saw a 10.2% rise in passenger numbers and at Glasgow traffic was up 4.6%.
However, traffic at Stansted continued to slide, going down 4.7%, at Southampton there were 1.7% fewer passengers last month and at Edinburgh, which BAA has been ordered to sell by the Competition Commission, numbers fell 2.8%.
