Skyteam FRA - GRU with stop in US, $600 3.0cpm
 

This is the infamous Europe-South America fare that has been around for quite a while. I just priced FRA-MSP-GRU-ATL-FRA for $600 in April/May. Needs to get booked through a travel agent to get that price. Yields 20400 MQM.

At $600 this is all in economy, right, not a mixed class itin? GF is confusingly showing J/F seats ("lie flat", "angle flat" etc) next to "economy class" for many of the legs on the link you posted.

You can do SCL and EZE for a bit more money. You can ticket this via orbitz.

Yes, this is all economy. I booked a similar itinerary (different dates) in J with stopovers in both directions for about $2200.

Thanks , thats a nice trick , i was always trying to book something like this but DL website dont allow such compex booking

I even found a masterpiece , check it

Two issues are a night in MSP and a good pray to avoid IRROPS , i would like to see the face of DL agents when they will see such booking
