Hmm. Business class fares are typically OUTRAGEOUS! What would you consider to be a typical fare? 4k? 5k?
I think there are business class consolidator fares out there...but I don't know where to find them.
How about using some miles? That seems to be the most popular way.
If you don't have enough miles and can't find something more affordable, drop me an email and I'll see if I can help in some way.
