Malaysia Airlines chief executive Peter Bellew is to step down from the airline after barely a year, having been recruited by budget carrier Ryanair to serve as chief operations officer.
Bellew had previously been Ryanair's flight operations director before joining the Malaysian flag-carrier two years ago, and subsequently being appointed to head the airline last year.
But Ryanair says he will rejoin the budget carrier from 1 December.
Bellew's recruitment follows the sudden departure of operations chief Michael Hickey in the wake of the enforced mass cancellation of Ryanair services over a pilot rostering issue.
Ryanair says Bellew will be tasked with ensuring that the "rostering failure" which emerged in September will "never be repeated".
