Each air carrier, foreign air carrier, and ticket agent that operates an EAIS must comply with the requirements of this section.

Each EAIS that uses any factor, not based on user selection or corporate contract travel arrangement, directly or indirectly relating to carrier identity in ordering the information contained in an integrated display must clearly disclose as provided for in § 256.5 that the identity of the carrier is a factor in the order in which information is displayed.

An EAIS's integrated display must not give any carrier's flights a system-imposed preference over any other carrier's flights in that market based on carrier identity unless the preference is prominently disclosed as provided for in § 256.5.

Each EAIS must display information in an objective manner based on search criteria selected by the user (e.g., lowest fare, lowest total cost, date and time of travel, class of service, stopovers, total elapsed time or duration of travel, number of stops, limitations on carriers to be used, particular airport(s), number of passengers, etc.) When providing information in response to a search by a user of the EAIS, the EAIS must order the information provided so that the flight options that best satisfy the parameters of the user-selected search criteria are displayed conspicuously and no less prominently (e.g., in the same or larger font size and the same or more noticeable font color) than any other flight option displayed. Flight options may be presented in sequence, matrix, or other formats, but the flight options that best satisfy the parameters of the user-selected search criteria must be ranked in lists above other flight options, or identified more prominently than other flight options in a matrix or other format. This does not preclude systems from setting default display parameters that are not deceptive or offering users the option to choose a variety of display methods within those parameters.
