UK airports operator BAA has reported record traffic figures for July but it added that the London bombings had affected domestic travel.
Domestic air travel rose just 1.4%
It said 14.6 million passengers used its seven UK airports last month, up 2.6% on July of last year.
However, it said domestic travel had been affected by the London bombings of 7 July as people cancelled trips.
BAA said domestic travel was more affected than long-haul "but we are seeing a pick-up already".
Mark Mann, a spokesman for BAA, said "people who had committed to a long-haul holiday, for example, to Dubai or the US, generally went ahead with it.
"But some of those planning business trips involving domestic travel decided to reschedule or to conduct business over the phone."
Passenger numbers at London's Heathrow airport were 6.46 million in July - down 0.6% on a year ago.
North Atlantic passenger traffic increased 1%, BAA said, while other long-haul traffic rose 7.5% and Irish traffic added 8%.
But domestic traffic rose a lower-than-expected 1.4%, while traffic to European Charter markets continued to decline, falling 5.5%.
Mr Mann said that "when you look at the figures as a whole, things are still very good. It's our busiest July on record."
Foreign tourists made 14.01 million trips to the UK in the first six months of 2005 - 12% more than in the same period a year ago, according to the Office for National Statistics.
Overseas visitors spent £6.11bn in the first half - 12% more in 2004's first half.
Visitors from North America dropped 6% to 1.96 million in the first half of this year, but Western European visitors rose 12% to 9.2 million, while visitors from the rest of the world soared 30% to 2.85 million.
