I booked JFK-UIO for 4 pax in November for $770 p.p. Connection in BOG with good (2hr) connection times. Seems to be really good availability throughout the year at the same price every day. It is a very decent fare.
There are two A330 flights a day on the 5.5hr JFK-BOG leg - one is a newer lie-flat and one is angled-flat. Going out the angled-flat is overnight and the lie-flat departs early morning. The lie-flat times are less convenient on the way back with 3.5 hr connection in BOG and a 4.25am arrival in JFK, so I went for angled flat that gets in at 9.00pm instead. BOG-UIO is a 1.5hr flight on A319 or A320 recliners.
The price on Google flights shows at around $710 but then jumps to $770 when you click through to book. It is bookable directly on Avianca, though I did it through Orbitz.
