Many years ago, pre 9-11, the RT ticket from SAN to IAD was ~ $2K on AA or United. Since then I have paid as little as $395 and as much as $850 for the same journey. I'm sure the variables are all over the place but I wonder what the Airline needs to make per seat be profitable?
Rodsrsr - I know you're just being hypothetical but anyone creating/participating in an on board "ugly" situation will likely be arrested and if possible bum rushed off the plane by unfriendly folks in uniform. There are lots of road warriors out there who indeed need to work while in transit.
