Speaking in an on-stage interview at Routes Europe in Hannover, Tui Fly managing director Oliver Lackman said providing the issues have been resolved on the aircraft, which has been grounded globally following two deadly crashes at the turn of the year, he would be happy to use it.

But he added first of all consumers would need to be reassured of the aircraft’s safety and this could be done by explaining to them what went wrong in the first place, how the issue has now been resolved and that there is now confidence that another crash won’t happen.

Lackman said: “We have to work on it first of all, the manufacturers have to work on it and we as an airline have to work on it.

"It is all about confidence and trust.”

The grounding of the aircraft is expected to cost Tui, which operates 15 of the aircraft with another eight scheduled of delivery by the end of May, €200 million and Lackman said the airline had to move quickly to lease additional aircraft to cover the holes in the operator’s summer schedules.
