Pre-Covid, I used to buy tickets from JFK - PVG - MNL on China Eastern for $2,400 round trip in business class. Now I’ve noticed that airlines like China Eastern and Hainan post $20k for the same seats. They even charge like $6k for economy. There is no way they are really selling these fares. I can only assume they are selling all their inventory through tours and travel agencies (consolidators). How do I get a hold of the right people to find the real fares on China Eastern, China Southern or Hainan?
