Lima has been a hard ticket to find real discount fares on in the past two months. So, I was surprised to see on Google Flights an American Airlines-Copa flight at $446 for Miami to Lima via Cancun. American Airlines is Oneworld and Copa is Star Alliance.
After investigating a little more closely, this real deal hacker fare turns out to be a $218 Copa round trip fare between Cancun and Lima. American Airlines has some low fares to Cancun from around the USA. This provides an opportunity to buy a round trip ticket to Cancun and pick up the Copa flight for $218 for round trip Cancun CUN to Lima LIM.
Copa has the Cancun – Lima route on sale for as low as $218 for dates in every month from June through December 2015.
This reduces the cost significantly for a direct USA-Lima, Peru ticket with the addition of a trip to Cancun, for a day or two or a week or two depending on your desires.
Los Angeles – Lima, Peru
Copa Airlines $702 lowest fare over next four months.
Hacker Fare is Two Separate Tickets to have a trip to Cancun and to lima for less than one ticket direct to Lima, Peru.

(4 weeks for a long trip.)
This trip is nested around a separate Copa Airlines CUN-LIM ticket.
The Copa Airlines ticket was listed on Google Flights for $248 but came out to $293 for dates I tried.
Total ticket price is $643 for this itinerary LAX-DFW-CUN-PTY-LIM-PTY-CUN—PHX-LAX.
Copa does have lower fares. You need to play around with dates.
