You may fly non-award legs between the award flights, i.e., fly SKCL-SEQM, then fly a Friday Night Ops (FNO) in the USA, then fly SEQM-SKBO. (Pilots are not required to fly from the award airport to the non-award airport (i.e., SEQM to the FNO departure airport and then fly from the FNO arrival airport back to SEQM, but you are welcome to do so). Use UAL liveries for all flights; fly charters for flights not on the vUAL schedule.

Some notes on the airports:
Lima, Peru - Jorge Chávez International Airport, Peru's main airport; FS9/FSX/P3D still use SPIM. In P3D, SPJC is a small, high mountain dirt airstrip. Either ICAO code is acceptable
Quito, Ecuador - SEQM - does not exist in MS/Lockheed based sims; you'll need to download freeware or payware to put an airport where SEQM should be.
- Freeware option: https://library.avsim.net/download.php?DLID=216945 The install looks daunting but only because the scenery maker gave you a lot of options. At the end of the day, it's a pretty standard install if you read the readme - html version - file.
Payware option: https://www.flightbeam.net/seqm.html/ by Flightbeam; they never disappoint...
