Cargolux is to hold a board meeting before giving details of the preliminary agreement aimed at settling the dispute over delivery of its first two of its 13 Boeing 747-8 freighters.
The Luxembourg-based cargo airline, part-owned by Qatar Airways, said it had reached a "tentative" deal with Boeing regarding the "contractual issues" which had resulted in the carrier's rejecting the aircraft shortly before delivery last month.
Initial handover was planned for 19 September with a second scheduled two days later. Neither aircraft, however, has been delivered.
Flightglobal understands that the dispute has centred on performance improvement packages for the General Electric GEnx engines on the type.
The carrier said it would disclose further details of its agreement with Boeing after signing an accord and holding a board meeting on 7 October.
Cargolux was one of the first two customers to commit to the 747-8F in 2005, with an initial deal for 10 which it increased to 13 in 2007.
