A quarter of Brits were affected by the six days of closed skies, according to research by TNS Research International.
TNS RI Travel and Tourism found that almost 3 million Brits were affected, broken down to 8% prevented from flying and 19% indirectly affected by family being unable to fly.
More than a third (34%) of people interviewed said they or a family member could not return home on a scheduled date and 25% had to cancel or postpone a holiday.
Despite this, 70% of participants agreed that the flight ban was the right course of action and 46% said they were not put off to fly for their summer holiday this year.
“There is continued uncertainty over the extent of the impact on taking flights and overseas trips for the rest of 2010, although it is interesting to see that the majority of travellers will not let the situation influence their future plans,” said Head of TNS RI Travel and Tourism Tom Costley.
