Sir, – You inform us that the DAA earned €36 million from airport car parks in 2015 (Business, December 4th). That revenue figure is likely to have risen in 2016. The DAA charges up to €4.50 an hour and up to €40 a day in Dublin Airport, and in Cork airport €2.50 an hour and up to €17.50 a day for short-term parking. Might I suggest that the DAA and indeed many hospitals are "earning" too much and should consider reducing their charges? – Yours, etc,
JOHN MURRAY,
