Willie Walsh, chief executive of British Airways owner IAG, said Friday that he was "very confident" that London and Brussels would reach a "comprehensive agreement" on post-Brexit aviation.
Walsh, speaking at a relaunch of global airline alliance Oneworld, added that a chaotic no-deal Brexit would not deter passengers from flying.
"I remain very confident that we will see a comprehensive agreement between the UK and the EU on aviation," Walsh told journalists at the event in central London.
"I've seen nothing to suggest that confidence is misplaced." He added: "Aviation has been one of the best successes of Europe and it will continue to be after Brexit; we will continue to see flights operating, and I think everybody is clear on that at this stage."
Questioned about the industry impact of a disorderly no-deal Brexit, he replied: "I don't think it's going to have any impact on passenger numbers."
