Understanding Fare Construction and Searching for Published Fares

In the realm of frequent travel, mastering the intricacies of fare construction can unlock hidden opportunities and savings. Today, we delve into the world of fare analysis, drawing insights from a comprehensive guide shared at Frequent Traveler University Advanced.

Introduction to Fare Construction

Fare construction, although not an everyday necessity for most travelers, holds immense value in certain scenarios. While automated travel search engines often excel in speed and efficiency, human intervention can sometimes uncover overlooked opportunities. Understanding fare construction becomes particularly relevant in situations such as:

  1. Optimizing Cost: When seeking to lower the cost of an existing itinerary found through platforms like ITA Matrix, ExpertFlyer can quickly identify potentially cheaper published fares, providing alternative options without exhaustive manual searches.
  2. Deciphering Price Changes: In cases where a flight replacement or date change unexpectedly doubles the price, deciphering fare rules becomes crucial. ExpertFlyer aids in understanding the underlying reasons, preventing blind guesses, and facilitating informed decision-making.
  3. Exploring Flexibility: For travelers seeking same-day flight changes to enhance their journey, ExpertFlyer’s availability information can unveil additional options beyond the scope of conventional airline offerings, enabling smoother transitions and potential upgrades.
  4. Navigating Award Travel: While not all airlines display award space on ExpertFlyer, grasping fare construction principles proves invaluable in booking award tickets. By aligning fare rules with availability, travelers can optimize their award travel experience.

Searching for Published Fares

Initiating a search for published fares involves entering departure and arrival airports, along with travel dates, akin to standard search procedures. However, the focus shifts from immediate booking to obtaining a list of available fares for analysis.

Key features of ExpertFlyer’s search interface include:

  • Ticketing Date: Allows flexibility in selecting the date of ticket purchase, considering advance purchase restrictions.
  • Airline(s) and Cabin Class: Enables filtering results based on preferred airlines and cabin classes.
  • Class Code: Identifies different booking classes utilized by airlines, each with distinct pricing and rules.
  • Validate Fares: Confirms the validity of displayed fares for selected travel dates, filtering out potentially invalid options like those with blackout dates.

Upon performing the search, results are presented in a tabulated format, featuring fare basis codes, airline information, trip type, and pricing details. Notably, fare prices may exclude certain taxes and surcharges, necessitating careful consideration for accurate cost comparison.

Deciphering Fare Rules

While fare search results provide initial insights, comprehending fare rules unveils deeper nuances essential for informed decision-making. Key sections of fare rules include:

  • Eligibility: Specifies booking restrictions based on dates, times, and applicable fare types.
  • Stops and Transfers: Clarifies limitations on connections and stopovers, crucial for itinerary planning and compliance.
  • Combinations: Outlines permissible fare combinations, facilitating flexible travel arrangements, particularly for round-trip fares.

Understanding these rules empowers travelers to optimize their itineraries, considering factors like stopover durations and fare combination possibilities.


In today’s discourse, we’ve elucidated the fundamentals of fare construction and searching for published fares, laying the groundwork for informed travel planning. Tomorrow’s discussion will delve deeper into flight availability analysis, harmonizing with published fares to craft seamless travel experiences.
