CR,
For November, maybe 1/3 of the JFK lines were broken up. We just switched from PBS to Line Bidding for November as part of the new contract so everyone is on a learning curve. Personally I choose the 17 day lines so I only have to adjust my body clock once a month. I've been home a day and am still 7 or 8 time zones off. Hey, I'm up posting at 3:30 in the morning. Some guys bid MIA because the trips tend to be more broken up and most of the flying is north/south so less stress on the body. In the end you get what you can hold.
