The growth was driven by the Latin American & Caribbean and domestic sections, jumping 14.0% and 6.1%, and were offset by negative results in the rest of the sections.

The FTSE 100-listed firm lowered its 2019 guidance last month, with capacity expected to be around 4% rather than 5% as set previously.

The 2019 operating profit before exceptional items is expected to be €215 million lower than 2018 pro forma, at €3.4bn, following strikes and “additional disruption” affecting British Airways.

Shares were up 2.49% to 466.04p on Monday afternoon.
