Kolkata to Hanoi is down to ₹15,018 one way, which is a fair way under what the route has been asking lately.
Long-haul fares are usually the last to move, so a drop like this is worth a second look. It is close to the lowest this route has gone in the time we have been watching it. Either way, the price is live and it is the price we saw.
What to check before you pay
- Check the date on the search results before anything else. Error fares are often only wrong on specific days.
- The fare is one way. A return at the same price is not guaranteed, so price it before you commit to dates.
- The booking link goes to aviasales, which is where we found it.
Visa
Indian passport holders can apply for this destination’s visa online. Apply before you book non-refundable extras, because approval is not automatic.
If the price has gone back up by the time you look, leave it. Fares like this come round
again, and the desk posts them as it finds them.
Before you book
The price you see on this page is the price we saw when we wrote it up. Fares like this
are usually priced wrongly at the airline's end, and they get corrected when someone
notices. So the fare may already be higher, or gone, by the time you look.
Open the booking link, check the date, and look at the price before you enter any card
details. If it has gone back up, leave it and check the board again later. There is
always another one.
Book directly with the airline where you can. If something changes with
the flight, it is far easier to sort out with the people operating it.
Questions people ask
Is this fare real?
It was when it was checked, and the link on this page goes to the exact route and date.
It is a live fare, not a screenshot, so it can move.
How long will it last?
Anywhere from a few hours to a couple of days. Error fares tend to be pulled once the
airline spots them, and the very cheap ones go first.
Can I book a return at this price?
The price shown is one way. Sometimes the return leg is priced normally, so check both
directions before you commit.
