How to transfer from Xiamen to Manchester, England via Hong Kong?

Of course, you need a plane ticket from England. You should buy it before you arrive in Hong Kong.

You can buy Xiamen to Hong Kong, Hong Kong to London and London to Manchester City.

Or buy Xiamen to Hong Kong, and Hong Kong to other big cities in Europe, such as Amsterdam in the Netherlands, Frankfurt in France, Munich in Germany, etc. ), and then from these places to Manchester City.

If I remember correctly, there is no direct flight from Hong Kong to Manchester City.

Because it is not a joint ticket. You can take out your luggage in Hong Kong and get it back at the customs.
