Where to find lowest one way fare from Lima to Buenos Aires?

Question

I am traveling from Lima to Buenos Aires, but I found one-way fares are significantly more expensive than round-trips with LAN, TACA, and Aerolineas Argentina (if booked on their websites). Does anyone know where to purchase cheap one-way airfares? Thank you in advance!

Answer 1

well the cheapest way is by bus travel in Ormeno one way around 140 dolars, is up to you take like 3 days to get Buenos Aires, good service and good for budget bagpackers.

If you travel one way by air is the same if u buy a round trip air ticket there is no much difference.

Answer 2

Look in your local news paper for bargain fares, also go to a travel agent and let them do the search.  Also try expedia.com, kayak.com
