Some advice please.

I'm flying to New Zealand from London with a stopover in Langkawi soon. MH have allocated me 60A, the first of the seats at the back of the 747-400 where the configuration changes from three to two abreast.

Does anyone have an opinion on this seat. I realise that I'll be about the last off the aircraft. It seems that the chance of an emergency exit is non-existent and a bulkhead is slim. Would you try to change. Perhaps if 60B remains empty I'll have tons of room.

TIA

Simon
