- Change 1
Change 1 keeps the existing pnrsPNRs. This is an in-place modification of an existing process and existing pnrsPNRs. There can be removal of pnrs of PNRs or additional pnrs additional PNRs added to the itinerary based on adding/removing segments from different providers that result in either a new provider being added or all segments in an itinerary for a particular provider being removed. But this is all maintained within a single process and from our perspective and the users perspective they are modifying an existing itinerary. - Change 2
Change 2 is a total cancel and creation of a new process. Due to limitations on our side, we cannot handle changing an air segment through the change 1 flow where the destination changes. In this case the user is pushed down the change 2 path. The existing process/itinerary that the user has selected will be completely canceled along with all pnrs all PNRs in the itinerary. A new process and itinerary will be created for the expected resulting itinerary. First the new process is created and then the old one is canceled. This results in two processes in the upcoming reservations, one of which is canceled.
