Thanks for the links mechteach. I did a quick search on flyertalk without uncovering any specific threads on the two business classes (though I'm sure they're out there). The pictures you sent have really sold me. This trip keeps getting better and better.[/QUOTE]

There are plenty of comparisons on UA forum, on NZ forum and Star Alliance forum. There are also lots of trip reports on flying NZ trans-tasman (and also on the business premium product longhaul).
