You will have more then wounds time like others have said even if the FP line is back way up, ( the FP line will move faster if this happens, I think the longest I have spend in FP line was about 20 minutes) and even if there is a stop to let someone on that takes a longer time you are looking at maybe 30 minutes altogether ( and that is stretching it,( get there a little early and you should have time to take pictures and use the restroom on your way to BOG, and get lost.
