You might be able to find a current Air China promo on trip.com by simply switching countries in your account settings.

They used to have BUD-CKG in the list of flights to chose from as well.

When it comes to flying Air China Long-Haul with ratted/worn out Triple Seven, A330, B747 I am with you, but the A350 and the Dreamliner are fantastic.

Btw. somehow Trip.com manages to offer really steep discounts for international flights starting in the semi-official 17. federal state of Germany, also known as Palma de Mallorca.

How they manage to achieve that in the background is beyond me, because one does not have to return to PMI, but can finish the trip in Germany, Austria etc. and the first leg is with Ryanair, Air Europa or Eurowings to either Germany, UK or Mainland Spain.
