Almost. The Export-Import Bank of the United States provides cheap credit facilities to Boeing customer airlines, it is designed to assist US company exports. Generally, these airlines have to government backed/owned or investment credit rated. ANZ has used the Export-Import Bank for aircraft financing.
Generally perhaps, but the significant support that EXIM has provided in financing Lion Air's large Boeing order book (a privately held, Indonesian airline competing with majority state owned Garuda Indonesia that in all likelihood would have an 'interesting' credit rating) I suggest happens a fair bit.
Got to love the "free market" bahahaha.
But good on Air NZ, it's hard to knock Fyfe in how he took the batton from Norris and kept things moving forward. But I think Luxon really sees a plausible growth strategy for the 'end of the line carrier' and I think it's exciting times ahead.
