****UPDATE: Malaysia Airlines has now confirmed that it will "resume flying its normal route" between Kuala Lumpur and Europe from the evening of January 6, with normal baggage allowances also having been restored - click here for more information.****
Malaysia Airlines has placed a temporary ban on checked luggage on its flights into Amsterdam and Paris.
The ban had also affected flights into London Heathrow, although the carrier's Twitter page now says that "normal baggage allowance on flights to LHR operated by the A380 aircraft has been restored".
It's not entirely clear why the ban has been put in place, although media outlet abc.net.au reports that the carrier is citing "temporary unseasonably strong head winds" which is "limiting the airline's ability to carry baggage in cargo".
The differing aircraft used on the carrier's European flights may have a bearing on why the restriction has been lifted on services to London - MAS flights into Amsterdam and Paris are served by Boeing B777 aircraft, whereas those to London are operated by the Airbus A380 superjumbo.
According to the carrier's travel adivsory page of its website, the checked luggage restrictions "apply for flights to Amsterdam and Paris on 5-6 January 2016".
It is understood that these flights are operating with carry-on luggage only, with any checked luggage remaining in Kuala Lumpur to be sent on at a later date.
Travellers are advised to check with the airline prior to departure.
