Airline bosses have changed government policy for the second time in a month.
In April the Civil Airline Authority was pressured into easing rules that – for safety’s sake – stopped planes flying through any volcanic dust.
BA and other airlines simply put planes in the sky and dared the authorities to bar them from Britain.
Instead of confronting the bosses, “a safe level” was fixed.
But bosses such as Ryanair’s Michael O’Leary deemed even this concession too onerous when this week’s reading exceeded the agreed level.
Once more the pressure went on and once more air authorities caved in and doubled the “safe level”.
Passengers and airline staff have a right to demand that their safety comes before the profits of the airlines.
