British Airways owner International Airlines Group carried 3.4% more passengers in October than the same month last year.
The growth saw more than 10.3 million passenger travel with IAG airlines in the period.
BA saw carryings edge up by 1.1% to 4.17 million passengers in October to reach 40 million in the first ten months of the year, a rise of 1.2%.
Aer Lingus carryings for October also rose by 1.1% to reach 1.02 million.
The group expects to trim capacity growth to 3.4% a year up to 2023 against a previously planned increase of 6%.
However, average annual capital expenditure is set to rise by €4.7 billion against €2.6 billion for the 2020-2022 period.
An operating profit margin of 12%-15% is expected.
IAG said as it hosted a capital markets day: “In common with several other European and North American airlines, IAG will no longer disclose monthly traffic data from January 2020 but will instead report traffic data on a quarterly basis.”
