As an example, I found seats departing Los Angeles LAX on Sunday, September 1, returning from Bogota BOG on Tuesday, September 10.
Other dates are available for travel in September and early October. Travel to Colombia on Saturdays, Sundays, Mondays, and Tuesdays. Return from Colombia on Tuesdays, Wednesdays, and Thursdays.
This price includes a carry-on bag plus one small personal item. A checked bag costs $30 each way.
Standard advanced seat selection is included.
Copa Airlines is selling a $406 roundtrip fare with plenty of availability for travel in April, May, and late August through mid-December. Copa's fare also includes one free checked bag so it may be a better choice if you need to bring extra luggage or want to travel at other times of the year.
