Due to or because? Two ways to give a reason

When Air India announced that it would cancel 22% of its domestic flights for June and July, the coverage was full of reasons — soaring jet-fuel prices, a conflict near the Strait of Hormuz, and costs the carriers simply could not absorb. In English, the words you choose to introduce a reason depend on what comes next.

Because introduces a full clause (a subject and a verb). Because of and due to introduce a noun phrase, which has no verb of its own. The meaning is the same; the grammar is not.
