Questions & Answers about Mặc dù chuyến bay đã đến nhưng hành lý chưa đến.

Why does Vietnamese use both mặc dù and nhưng here? Isn’t that like saying although ... but ... in English?

Yes, it is very much like although ... but ..., and that is normal in Vietnamese.

• mặc dù introduces the concessive idea: although / even though
• nhưng introduces the contrast: but

So Vietnamese often uses the pair:

• Mặc dù A, nhưng B.

This is a very common structure.
Unlike standard English, where although ... but ... is usually considered redundant, Vietnamese often keeps both parts for clarity and balance.

You may also see one part omitted in some contexts:

• Mặc dù chuyến bay đã đến, hành lý chưa đến.
• Chuyến bay đã đến nhưng hành lý chưa đến.

All of these are possible, but the full pair sounds very natural.

What exactly does đã do in đã đến?

đã is an aspect marker that often shows that something has already happened or was completed before now.

So:

• đến = arrive
• đã đến = has arrived / already arrived

Vietnamese does not conjugate verbs the way English does, so words like đã, đang, and sẽ help express time and aspect.

In this sentence, đã đến tells you the flight’s arrival is already completed.

Why is used for the luggage instead of a negative like ?
