difference of "due to" and "be + doing smth"

[lawyerquang]

Who can tell me the difference between "be + doing sth" used for future tense and "due to" in the meaning of being going to do sth with the detailed and specific plan?
thanks,

"Due to" is another way of saying that something is a consequence or result of something else.

i.e. "The trip was cancelled due to the weather." - the weather was the reason the trip was cancelled.

"be+ doing something" is a completely different construction, not related in meaning.

Hi lawyerquang
.
I suspect what you're referring to is probably simply the adjective due, which can mean 'scheduled or expected' and is usually connected with some kind of official arrival time:
"Their flight is due (to arrive) in less than 10 minutes." = "Their flight is scheduled to arrive in less than 10 minutes."
.
Using the present continuous to talk about the future refers to a specific plan: "I'm flying to London next Tuesday."
