The latest figures were released by the Office for National Statistics. You can see its latest inflation chart here.
The late timing of Easter in 2011 helped push air fares down over the month, compared to the same two months last year.
A statement from ONS said: "By comparison, Easter in 2010 was much earlier and did not affect the April 2010 figures. The timing of Easter thus contributed to air fares falling by 11.1% between April and May 2011 whereas fares rose by 6% between the same two months in 2010. Similarly, sea fares fell by 14.7% between April and May 2011 compared with an increase of 1% per cent a year ago.
