The Max was grounded worldwide in March following two fatal crashes. A probe has centred around one of the aircraft’s deep-seated control systems. Boeing is working on a software update.
Last month, Tui Group chief executive Fritz Joussen said Tui would need to know by the end of May when the Max would be airworthy again if it was to reintroduce its 15 Maxs this summer.
He added there were two scenarios for its Max operations: “July, or not at all for the summer season.”
Iata has since confirmed it does not expect the Max to re-enter service until at least August.
