I have been advised by our aviation team that this tour is currently being operated with Vietnam Airlines who do not currently offer an online check in.

In terms of a flight upgrade, unfortunately we don't have a flat price list, these are based on availability with the airlines and can fluctuate. I would recommend that your contact your travel agent who will be able to discuss this with one of our holiday advisors.

Kindest regards,

Julia

and is it possible to get prices upgrade of seats ? 

Thanks
