Abstract: A travel forecast and allocation computing system and method for prospective and other travel purchasers to access for requesting, receiving, and re-allocating rights to travel on passenger transportation vehicles, whereby a travel purchaser may have an opportunity of re-allocating its purchased right to travel to one or another of travel purchasers by trading it, and whereby a travel provider may have an opportunity of efficiently allocating transport to service binding travel requests and have further opportunity of relief from providing changes to reservations. The present invention makes possible economic incentive for travellers to forecast their own travel behaviour, and enable economic incentive for travellers to commit far into the future to specific travel so that airlines need not rely on their own forecasting of demand to plan their operations.
