3819638 - Why do I see mixed cabin flights in Concur?

When searching for flights in Concur Travel, results are retrieved from Global Distribution Systems such as Sabre. These systems return priced itineraries based on availability, fare rules, and optimization logic.
 

In some cases, itineraries may include different cabin classes across segments (also referred to as mixed cabin itineraries). For example, one segment may be booked in First Class while another is in Premium Economy.
 

A key concept in evaluating these itineraries is the Most Significant Sector (MSS). This refers to the longest or most important segment of a journey, which is used to determine whether the itinerary meets the requested cabin criteria.

This article explains why mixed cabin itineraries (e.g., First Class combined with Premium Economy) may appear in Concur Air shopping results. It clarifies how these results are evaluated and what users should expect during the booking process. , KBA , CON-SRV-TRV-ADM-LAN , View Airlines , CON-CA , Cross Applications , Problem
