Some early moves in the list of leading travel sites in the UK as the gloomy winter makes way for spring and post-Christmas sales rush subsides.
In the agency category, Thomson continues its long run at the top of the charts but fellow vertically integrated travel brand Thomas Cook has lost out to Expedia in the battle for second place and the gap has narrowed at the top.
Thomson's lead over second spot was down from around 3% to less than 2% market share in March.
Ryanair, meanwhile, is around 1.5% market share behind arch rival EasyJet and 2% ahead of British Airways in the airline category.
