title: How to get PNR expiry
body: <p>Is there any way I can get expiry date of PNR or maximum time allowed for booking in Sabre's Bargain Finder Max Query? I need to get the expiry of PNR which is provided by airline. Is their any SOAP or Rest api available to get this information? It would be better if anyway I can get the expiry in BFM results.</p>
