More a curiosity: Booked AKL-MSY via LAX on NZ and paid to upgrade the UA flights LAX-IAH-MSY and back a week ago to First, did seat select etc, but the NZ site still lists those flights as being in Economy with the original seat selection. I'm sure it will be fine, but it is strange that it hasn't refreshed (it did when i did seat select in the first place through the United site)
