I was on a flight that was codeshared with Air NZ. So my ticket was Air New Zealand. At the time of checkin online, the option to select a seat is not available either on the Air New Zealand site or Singapore Airlines site due to the code share issue. What that meant was that I was preassigned a middle seat -- something that is uncomfortable due my height. It is a pity that the systems are not set up well. The flight itself was pretty good. New entertainment system, etc. Cordial staff, decent food. And flight landed earlier than the time...
