Great news!
Asiana is already my favourite airline for coach travel and I've seen for myself how marvellous the crew can be in comforting and entertaining older children.
I'm particularly delighted as there are others like myself who have experienced difficult pregnancies. Basically, we stop travelling so much in the critical year before we need to fly with our babies. This means no FF status just when we could do with it most.
Asiana's scheme (which seems to include unpublished lounge access) pretty much compensates for this as well as offering the chairs, slings and nursing covers.
I'll be travelling with my daughter from Europe to Japan next year - OZ is most definitely my first choice for the journey.
(Korean Air is a different airline - they may bring out a similar scheme as Asiana and Korean Air are rival companies in different alliances)
