I guess others probably know this, but maybe some don't..I never realized it until last night when I was playing around with trip planning in the future and maximum points available...
I have always figured that 3 year's was the maximum, bank one year and borrow from one year plus current year = 3 years...BUT
If you schedule your trip to straddle the end and beginning of your use year you could have 4 years of points to use on one trip...as the use year ends you use all your points from that year and banked points from the year before..Then at the start of the next use year you use all that year's points plus borrow from the next year.
Example: 220 points- August Use Year...
Schedule trip for end of July and beginning of August 2003:
Use 220 from Aug 2001 (that were banked into Aug 2002-July 31 2003) just be sure to use at LEAST 220 points in July. For the days in August use Aug 2003 points and Aug 2004 points...the Aug 2002 points can go on either side of July 31 as current or banked...voila- 840 points at your disposal for one trip....(but you will have to wait a while before you can go again!)
