DUBLIN, Oct 16 (Reuters) - The head of the global

airline body IATA said delivery delays from planemakers Airbus

and Boeing ( BA ) are "massively frustrating" and are

not yet getting better.

"It's massively frustrating for airline CEOs and it's having

a big impact," International Air Transport Association Director

General Willie Walsh told an Irish think-tank on Wednesday.

"It's going to be a problem I think for a number of years to

come. The message I get from airline CEOs is the situation

doesn't look like it's getting any worse, so it seems to have

bottomed out or plateaued, but it's not yet getting better."
