But do you calculate in the cost to get to your starting point?
Personally, I don't - I start at my local station
The Slidell loophole gets you a very high value, but many users here will FLY to the nearest airport, then FLY back home. Or, book a standard ticket to get to the proper zone. Seems you probobly need to factor in all the "side costs" to get an accurate number.
Since I don't do that, I don't have to.
We were thinking of using a 2-zone to go from Portland, Me to El Paso. Thats about ¢60/point, but the cost to fly back is about $400, making that rate closer to ¢40/point. Still pretty good though.
OK, lets assume you and your SO leave Maine on 28-MAR-09 - your trip in coach for 2 pax will cost $434 OR 2 times 8,000 points = 16,000 points - $27/1000 points OR 2.7 cents/point.
If you use a roomette, it will cost $1,005 or 20,000 points. making it $50/kilopoint or 5.0cents/point
If you use a bedroom, then it will cost $1,497 or 30,000Pts This comes to $50/kPts or 5.0 cents/point.
By my analysis, you get the most for your points with a roomette OR sleeper.
Food is another factor - but I don't want to go there. This type analysis is good enough to tell me what what I want to know.
Something to keep in mind is that the price of the trip increases as the time gets shorter and that makes a difference too.
