DUBAI, June 2 (Reuters) - Emirates President Tim Clark

on Sunday called on Boeing ( BA ) to compensate the airline for delays

in the development of the U.S. planemaker's latest 777 jet,

which the carrier has bought.

Emirates is refurbishing many of its existing 777 aircraft

as it waits for the new version, known as the 777x. Clark said

that Boeing ( BA ) should pick up the costs of the refurbishment.

He also told reporters in Dubai that Boeing ( BA ) could not say

when exactly the new 777x jet would start being delivered.

Boeing ( BA ) has said deliveries would start in 2025, five years

later than originally scheduled.
