VietJet (Hanoi to Osaka) Excess-Baggage Fees

Hi all,

My wife and I will be travelling from Hanoi to Osaka, as part of a larger trip.

We will be travelling with two carry-ons each.

I know our weight limit with VietJet is 7kg (per person) combined for carry-on weight.

However, our combined carry-on weight will be around 11kg (per person), so 8kg overweight for the both of us.

When I went to take a look at their excess-baggage fee I saw a section that said 315000 VND per excess KG (link below).

Can I please get a second pair of eyes on this? Is this information correct? Because that price seems like a LOT.

If it's accurate, should I maybe look at checking-in my carry-on baggage? It seems cheaper....

Thank you.
