Does this sound natural?

The price of single trip connecting flight to Xiamen is $400.

To be clear(er), I would prefer, "...a one-way flight", if that is what you mean.

No. For a start, you need the indefinite article before "single". Also, there is no such thing as a "single trip connecting flight" to anywhere. A single trip is one flight, with one departure airport and one arrival airport. A connecting flight is the second leg of a two-flight journey. For example:

London to Paris (single flight)
London - Paris - Hong Kong (two flights, with a connection in Paris)

London to Paris (single flight)

Isn't that a direct flight?

It is!
