British Airways has said its June passenger volumes fell 1.4% compared with the same month a year earlier, but it said premium volumes improved and market conditions were broadly unchanged.
'Non-premium traffic continued to show some comparative weakness on the North Atlantic and in short-haul domestic,' BA said in a statement.
The airline also said it was too early to assess the impact of the latest security measures at UK airports on forward bookings.
The airline cancelled 108 flights on Tuesday, out of about 450 worldwide, after a suspect bag at London's Heathrow airport forced an evacuation.
In June, 1.4% growth in premium traffic was more than offset by a 1.9% decline in non-premium traffic, causing its load factor - a measure of how well it filled its planes - to slip by 1.4 percentage points, to 80.5%.
