How long is the link in the e-mail active to the PNR?
For as long as the PNR is active in the Sabre system. Each time the itinerary is accessed using the link from the e-mail, the PNR is retrieved directly from the Sabre system. However, only active segments in the itinerary section of the PNR will be displayed on the Virtually There itinerary. Past-date segments in PNR history are not displayed. Therefore, if the traveler retrieves the itinerary in the middle of a trip, only future-date segments will display.
