Apologies if this is he wrong forum but I recently booked a flight with MH MEL-KUL, KUL-LHR and return in economy. I paid the relevant amount to reserve particular seats with the final leg KUL-MEL being 11K on an A330-300. It happens to be the front row in economy.

A friend decided he would like to travel with me and made the necessary arrangements on-line after I had given him my flight and seat numbers. When he came to reserve the seat next to mine for the KUL-MEL leg it showed on the webpage as "blocked". There were no problems with the other flights.

Would anyone be able to suggest a reason for this. I'm only OW Ruby so I can't see it being blocked for my comfort (although it would be nice to think so. )

Would it be worth calling the airline, explaining the situation (obviously at present they don' know we are travelling together as the bookings were made on-line and separately) and asking if the seat could be unblocked?

Thanks for any advice.
