As an Irish company, Europe's largest carrier by passenger numbers could require a UK air operating certificate, or AOC, to continue domestic services post-Brexit, Ryanair CFO Neil Sorahan told an airline conference, Bloomberg reported.

A spokesman for Ryanair confirmed the comments attributed to Sorahan.
