Britons stranded abroad after Europe's skies reopened are facing the prospect of being stuck for another week.
Travel chiefs bemoaned "a significant lack of air capacity" to beat the backlog of travellers waiting to get back after the volcanic ash brought European flights into meltdown.
With flights expected to run normally, Abta said it aimed to have repatriated more than 100,000 British passengers by the end of this weekend.
Mark Tanzer, Abta Chief Executive, said: "While most flights are back to normal, and most stranded British passengers will be back by the end of this weekend, there is still quite a high level of disruption in some destinations.
"In some areas of the world, there is a significant lack of air capacity to enable British people to be returned quickly."
Meanwhile, the RAF's Typhoon Eurofighters have been given the all-clear after tests showed volcanic ash found in engines caused no damage.
