My guess is Freedom. They need to replace the the 737 classic as we all know they aren't getting the A320's and the 7E7 performance and fuel economy will be perfect for that kind of operation.
hmmm, i could never see the 7E7 working for Freedom, i think they may go the Airbus way as well with the 319/320.
the 7E7 will be used for long range routes out of AKL surely, like Japan, China etc, and open up new opportunities.
really the fleet won't be THAT mixed will it? 777,7E7, 747 for long haul, with 747 to be phased out eventually, and airbus for the short stuff.
they are doing a big revamp of the '74 interiors with the whole ife upgrade and the like so can see them being around a while yet.
