Which lounges can Malaysia Airlines' Business Suites passengers use?

Spoke to Malaysia Airlines - changes won't apply retrospectively, so if you've made an F booking you will still be eligible for F Lounge access on OW partners.

I wouldn't put too much faith in MH when it comes to things like this, I get the feeling that what somebody there says and what actually happens can be two very different things.

Exactly and most importantly what everyone seems not to realise is that all ground services including their lounges and call centres are not run by MH but by a provider which has been outsourced. Only the aircraft and the flight crew are true MH operated and so when you get to the lounge, contrary to whatever policies are in place and being implemented by MH the staff will have no clue and they are most incompetent. For example all Oneworld Emerald members are entitled to fast track cards at airports where fast track services are available, for ex Bangkok but unless you fly business you will not be given one, even if you show them the MH magazine where the policy and benefits are clearly stated and even if you insist on speaking to a duty manager the ground staff at the gate will refuse even if they have plenty of spare fast track cards for Bangkok. Try their call centre, they misinform you best of cases and never keep their word or commit to anything they promise you on the phone. Complaining to the customer service centre will not get you any resolution either as all they do is send you a generic response. MH provides services that are appalling and not in line with Oneworld standards or policies, they are worse than a low cost carrier!

Hi 1Worldfreqflyer, just FYI, access to airport fast-track lanes isn't actually a guaranteed perk of Oneworld Emerald: access can vary from one airport to the next and can depend on which airline you're flying and/or any local government regulations.

You can search for a particular airport on the Oneworld website and it'll show you whether a), there's any fast-track facility available, and b), which airline(s) you have to be flying to be able to use it.

For Bangkok, the website shows that only Oneworld Emerald members flying with Cathay Pacific get fast-track, not Malaysia Airlines (or any other Oneworld carrier), so here, the staff were correct to decline the fast-track card.

(Obviously, it'd make the mose sense for this to be consistent across all Oneworld partners, but it's not, and has nothing to do with the "incompetence" of airport staff in this case.)

You are actually wrong and let me clarify. I did state that fast track access or cards are given to eligible passengers at airports where fast track is available. MH did write to me to confirm what is stated on the list of benefits printed in their in-flight magazine, including fast track access both upon arrival and departure in BKK, regardless of class of travel. And you are wrong yet again for all Oneworld carriers offer you a fast track card if you are Emerald upon departure fron or arrival into BKK including Qantas, Cathay Pacific, British Airways and JAL as I have travelled with them far too many times and this has never been an issue. I suggest you reread my comment again and if you are so happy with MH then by all means so be it, but I will no longer choose to support them when what they offer is in disarray and God forbid there is problem with your booking for you will then see how amazing their outsourced call centre is, but of course you must clearly work for MH that you are so defensive. Oneworld on their site clearly states that one of the benefits afforded to Emerald members across the alliance is fast track where the service is available available, like I had originally stated, Bangkok, London, Melbourne and many others, but not where it naturally is not available like Hong Kong or Paris etc. What part of this is so difficult for you to comprehend?!

Its so true that for MH, apart from things in the air (which were absolutely amasing per my experience!), everything on ground are just rubbish!!!
