The positive year-on-year figures for February end a run of 15 straight months of negative results, which must give some grounds for optimism.
However this small recovery is from an all-time low in Feb 09, when movements (-25.6%) and passengers (-23.9%) showed their greatest decline on the previous year's figures.
Taking a longer view, the latest figures are well below the numbers reported for Feb 05 (-11.0%, -10.1%), so perhaps it would be premature to crack the champagne!
