The code-share is due to come to an end in 2005 (as it started in 1995) I think. The Malaysian government and the UK govt are due to have talks about the ASA soon. Malaysia Airlines is pushing for a third daily service into Heathrow and a daily service into Manchester.
British Airways has expressed an interest in returning to Kuala Lumpur in 2005 as part of the new agreement.
Other carriers may be involved in the talks as Garuda Indonesia are looking to expand their current code-share with Malaysia Airlines into the UK which have so far been very successful. The Garuda-MAS 'airbridge' between Indonesia and Kuala Lumpur has seen traffic mushroom at KUL
over the last year and KLM is also keen to expand on this cooperation at KUL
We may also see Malaysia Airlines switching their UK partner to KLMuk with passengers feeding via AMS
instead of LHR
(and currently transfering on to bmi)... next year holds some interesting changes at Malaysia Airlines in Europe as the airline continues to expand in Europe after years of downgrading services to the West.
