I have only recently started looking into a trip to New Zealand from DFW. I'm looking at December 2024 at the earliest. What options should I look into for comfortable business class seats? It seems like United has DFW to IAH to AKL (on Air New Zealand) that seems reasonable but I see that the seats are "dated" per a quick look in other threads. Does Qantas (or another airline) have seats that might make sleeping so much more easier that any extra cost is worth it? What other variables should I consider when looking into the different routes/airlines? I have miles with AA but it seems like using that will be next to impossible.
