title: Air API to fetch flight class and its price information
body: <p>I am pretty new to using Sabre Air APIs. I am trying to do a proof of concept to identify the APIs that can be used to book a flight. Documentation recommends to use Orchestrated APIs to reduce complexity.</p>
  
  <p>My question here is about how to get flight class (eg economy, business etc) availability and its price information. I don't see those results coming from InstaSearch flight &amp; Bargain Finder APIs</p>
  
  <p>It would be helpful if someone can guide me on this.</p>
  
  <p>Thanks!</p>
