Thanks Bowman2. I live 10mins from LHR so may be useful. I am waiting to speak to the agent but as they are 12 hours time difference, it is proving challenging.
Having looked at various options including NAI, EK, EZY, Hanain, Korean, it appears that CSA suits me better on paper. Just need to work out between CAN, MOMO or RSP and then I may apply and then take on the selection challenge!
