The UK government is to offer greater financial protection for millions more package holidaymakers under the Air Travel Operators' Licence (ATOL) scheme.
Many holidays involving flights are covered against airline or tour operator collapses by the ATOL scheme, which is run by the Civil Aviation Authority (CAA).
However new government plans are now to include air travel trips that were not previously Atol-protected.
Aviation Minister Theresa Villiers said the proposals would cover up to six million extra holidays would be covered by Atol.
She said: "As we move into the busy summer period, millions of us will be heading abroad on holiday. While the chances of a holiday company going under are thankfully very low, the impact on those affected can be significant.
