BRITAIN’S air travel resumed tonight as some restrictions were lifted.

The Civil Aviation Authority (CAA) said UK airspace reopened from 10pm and

transport secretary Lord Adonis said that he expected all British airports to remain open.

CAA chairwoman Dame Deirdre Hutton said none of the no-fly zones caused by the volcanic ash cloud are currently over Britain.

The CAA said: “The major barrier to resuming flight has been understanding tolerance levels of aircraft to ash,” the CAA said. “Manufacturers have now agreed increased tolerance levels in low ash density areas.”

A spokesman for BAA, which operates airports including Heathrow, said it would

do everything possible to “get people moving”.
