Hello, i tried to buy a ticket with this airline but paying proved impossible...tried with 6 cards from different banks, all declined.
Tried with Alipay-does not work (says it does not accept non chinese-mainland cards)
Alipay HK i can't use because i need a HK local number.
Tried with Weixin pay, also says it does not work with foreign cards.
No other option available...
I am from Eastern Europe.
I can't get where the issue is: -maybe they just do not accept European cards or cards from specific countries?

The only solution would be to use an OTA, for ex i have found the flight on Trip.com or Opodo. I wonder if they are reliable, i have always avoided third parties and booked direct. I don;t even know how these platforms work, if i book with Trip.com, the PNR i get can be used directly with HK Express to check/manage booking?
