Do airlines check carry-on weight and confiscate items on flights from Nha Trang, Vietnam?

One traveler carried peeled dragon fruit in a plastic container in carry-on. At security, the backpack was turned inside out, the container was opened and inspected, then everything was returned without issue.

Another traveler flew with a travel bag as carry-on plus a separate toiletry bag (несессер) — everything was accepted without any issues throughout the process.

One traveler reported that carry-on was not weighed at all at check-in, even with both a backpack and a separate shopper bag. A practical tip was to avoid showing the extra bag directly at the check-in counter.

At security, a few small seashells in carry-on were allowed without issue. A 200 ml shaving foam also passed in one case, although items like this are safer in checked luggage because enforcement can vary.

Another traveler said a small backpack was accepted as carry-on, especially when covered with a sweater or jacket. However, hair mask and jam were confiscated at security, so thick cosmetics and food items are better packed in checked baggage.
