No-one is able to put a date on when flights will resume.

British Airways conducts test flight

Yesterday, British Airways chief executive Willie Walsh joined four crew in a three-hour test flight from London, over the Atlantic, to Cardiff. Today the airline will study the effects of the flight on engines before concluding whether it is safe to fly or not.

Volcanic ash travel backlog a concern

The BBC website reported John Strickland, director of the aviation consultancy JLS Consulting, as saying even when flights resumed, a backlog would still cause major problems.

“This is a really big headache, especially for long-haul operators,” Mr Strickland said.

“Airlines rely on a carefully-planned sequence of flights. Once the sequence is broken, it is very hard to catch up, particularly on complex routes such as the UK to Asia or Australia.”

And as more airports fall under the volcanic cloud, the problem will only get worse, particularly when those airports are international hubs such as Paris and Frankfurt, both of which were closed on Friday.
