Where is 0207 4239090 given? It's not in our database.  

There is an entry for Malaysia Airlines in the database with several numbers. Have you tried them?

Please let us know what works and what doesn't.

I have just called the 0870 607 9090 and 0871 423 9090 numbers and at the moment they are closed. Both answer with the same message giving opening times. It's quite a long one and starts off "Thank you for calling Malaysia Airlines." About 40 seconds in, it refers callers to the 0871 reservations number (even if you call the 0871 number) for any "urgent" matters.

The number which was in the database, verified, as being for tickets and reservations was 020 73412040 is now unobtainable.

I tried numbers 020 73412000 through to 2101 and many answer as 2000 does. That is a message which starts "Our office is now closed." Note that this is different to the one on the 0870 and 0871 numbers.

However, one does answer the same as the 087x numbers and that is 020 7341 2029. I have amended the database entry and would be grateful for any feedback as to whether this is indeed the alternative for Malaysia Airlines' 087x numbers.

The irony is, it's possible to call Malaysia for only 0.5p/min from a landline, yet to call the airline's advertised UK number costs 20 times as much!
