A small number of flights have resumed in northern Europe but the Icelandic volcano which has caused air traffic chaos for nearly a week continues to play havoc with air travel plans.
A lucky few managed to land at Charles de Gaulle airport in Paris this morning and the check-in desks were busy.
But British air traffic controllers are warning of a new ash cloud headed for major air routes, prompting British Airways to cancel its re-scheduled short-haul flights.
The tremors in the Eyjafjallajökull volcano have been increasing slightly but volcanologists say it is now producing lava which means less ash. The cloud is also at or lower than 6,000 metres.
The European aviation control agency yesterday agreed a deal with the European Commission to get European air traffic moving.
But as experts disagree over how to measure ash content and who should decide if it is safe to fly… it may yet be the volcano that has the last word.
