How is this sentence read?

It is read:

くうせき が できたら、まどがわ の せき に すわりたい です。

Word-by-word:

• 空席 = くうせき = vacant seat / empty seat
• できたら = if it becomes available / if one opens up
• 窓側 = まどがわ = window side
• 席 = せき = seat
• 座りたいです = すわりたいです = want to sit

A common reading point is 窓側: it is まどがわ, not まどかわ.

Why does できる mean something like become available here?

できる has several meanings in Japanese, not just can do.

Its core idea is often to come into existence, to be formed, or to appear. So in this sentence:

• 空席ができる literally means an empty seat comes into existence
• in natural English, that becomes a seat opens up or a seat becomes available

So 空席ができたら means:

• if a vacant seat opens up
• when a seat becomes available

This is a very natural use of できる.

Why is が used after 空席?
