I feel that if Air NZ and Virgin are going to sell seats for each other's flights then they need to suss out the interoperability.. having to call up to select a seat is very inefficient for passenger and call centre operator. I flew to from AKL to LAX via SYD with a friend a few years ago, to and from SYD was on Air NZ and to and from LAX on Virgin. Check-in for the first flight in Auckland (on Air NZ) was just a cluster .... because I had booked through Virgin's site and there were issues (friend's booking through his work was fine). And they were using some sort of DOS programme?

Then on the way back, more issues during check in at LAX..
