Geez United... how big? Bigger than Virgin Blue, smaller than QF. Bigger than Dragon Air, smaller than Cathay Pacific. Bigger than Silkair, smaller than SQ.
As mentioned, Air New Zealand is modest in size when compared to her major competitors in the region. Domestically, how big is New Zealand? It has more sheeps than people! So that would give you a picture of how big the airline really is.
Can ANZ grow? Probably, but after the recent turmoil, growth would probably be cautiously handled because they are obviously not ready for it. They were the 20th largest simply because they absorbed Ansett (then Australia's 2nd largest carrier). But now, they are back to where they were before, a small little international airline.
However, ANZ is excellent in the service it provides (tho some die-hard Ansett lovers might deny) and it remains that way. Lets hope they continue to shine.
Final note, let it go Desmond. Ansett is gone and ANZ has gone back to New Zealand. Stop stirring up shit.
