1, Malaysia Airlines/Thai Airways, small country, the cheapest. Besides, JAL is also very cheap. In the past, JAL was around 1200, and it seems that few people in China took the exam. As for which small airlines are afraid to sit.
2. Cathay Pacific/Korea/Dragonair is the choice of most people, because the service is better, the plane is better, and these airports are all in Chinese. I remember that Dragonair seems to be reasonable, too, which seems to be around 1500. Cathay Pacific in Korea is a little expensive, and the specific price is a little forgotten. Asiana Airlines seems a little cheaper than South Korea. China people mainly sit in these three houses.
3. Singapore Airlines is the most expensive, but their quality is also the highest (I have never sat on this, but the price is really around 2000). China Airlines seems to be quite expensive, too. (This is a company in Taiwan Province Province)
4. The worst choices are Air New Zealand and China Eastern Airlines. First of all, these two are not cheap (China Eastern seems to be 1500), but the models are not good (Air New Zealand is afraid to fly, China Eastern is Airbus). The service of China Eastern Airlines is also super poor.
There was no direct flight between China and New Zealand before. China Eastern Airlines made several direct flights to Auckland, and it was said that the response was good, and then it was gone. I don't know if there is a direct flight now. It should be cheaper.
6. Generally, it takes more than 20 hours, not counting the transfer time, and the fastest transfer takes 2 or 3 hours. However, if you don't buy tickets in advance enough, you may stay for a long time (maybe more than 20 hours) during the connecting flight, so you must book a hotel, or you will go crazy at the airport. In addition, it is best not to book hotels in airport hotels and airport hotel, which are very expensive.
7. The above prices are all discounted fares, so you can't afford the full price at all. Western Airlines is in the peak season, and the price will not rise sharply. The discounted prices are all the same. It should be noted that unless you have a relationship, it is difficult to book a discount within 1 month. Even if you book it, it's not good. Usually you book two or three months in advance, and the distance will be more reasonable.
Where do the airlines in that place transfer? Korea/Asiana is in Seoul, Dragonair/Cathay Pacific is in Hong Kong, China Airlines seems to be in Taipei, China Eastern Airlines is in Sydney, JAL is in Tokyo, Air New Zealand seems uncertain, and Seoul, Hong Kong has stopped.
