At Nha Trang airport, can you pay excess baggage fees in Vietnamese dong, and can you prepay extra baggage for a charter flight?

One traveler suggested checking the Trip (Trip.com) service, where extra baggage can sometimes be purchased online a few hours before departure. It's also possible to pay at the airport, but at a higher price.

For a return charter flight with a 20 kg allowance shared by two passengers, travelers report they could not arrange extra baggage in advance: the airline did not offer the service online and redirected them to the tour operator.

After contacting the tour operator, the answer was the same: no separate extra baggage purchase was available for the charter, and if the overweight was significant, passengers were told it would be handled at the airport check-in desk.

A practical scenario mentioned by travelers is that a small overweight bag may sometimes be overlooked, but a larger excess is likely to be charged at the airport, so charter passengers should not rely on being able to prepay for baggage beforehand.

A separate practical question for passengers departing from Nha Trang is whether excess baggage can be paid in Vietnamese dong on the spot rather than only in another currency or by card. The messages did not confirm the payment method, so it is safer to carry cash and have a backup payment option.

If your dates are flexible and you can depart within the next day or two, travelers note that cheaper flights sometimes appear at the last minute. This does not solve the baggage issue, but it may reduce the overall flight cost.
