Was looking around yesterday at prices for 4 of us for Christmas/New Years this year. Coach fares were from $1000pp to $1650.
The best flight for us is usually from San Antonio to Houston on what was formerly Continental, now United. Those fares were the highest. The $1000 flights involved going through Atlanta.
Just for goofs I checked on business/first class and found them on United for $1350pp, $350 less than coach! I nabbed them and went on later and they had gone up to $2150pp, I guess because I had bought 4 of the available seats.
Was going to wait, but couldn't pass up that deal, especially since my wife has a bum knee and we spent a bunch upgrading last trip around.
