The Global Business Travel Association "encourages" the Department of Transportation "to move quickly and require airlines to provide ancillary fee and fare information on any platform selling airline inventory

, not just airline websites," although GBTA is not "dictating specifics on how the fee data be transmitted or displayed," according to a statement. "In its next phase of rulemaking," the association stated, "we strongly encourage DOT to address the display of fees and fares at all points of sale. We will work with DOT to establish a framework for transparency so travelers and booking agents can understand the total cost of travel before buying a ticket."
