PDX BOG for $2500 for two people sounds like a great deal. I'm sure the earlier replies would have been more helpful to the OP if it had been clear that it was 2 fares.

Last time I flew BOG IAH the business was bog standard US first class so bank on a wider seat and food and drinks. It wasn't a bed BOG to IAH and I'm not aware of it changing but others fly UA to BOG more often than I do
