This rulemaking would collect more detailed revenue information regarding airline imposed fees from those air carriers meeting the definition of "large certificated air carriers." Many air carriers have adopted fees for such services as checked baggage, carry-on baggage, meals, on-board entertainment, internet connections, pillows, blankets, early boarding, canceling or changing reservations, unaccompanied minors, pet transportation, etc. The Department bifurcated its rulemaking on reporting of airline ancillary passenger revenue into two separate rules; one rule to address computation of mishandled baggage and wheelchair rates (2104-AE41), and this rule to address reporting of airline ancillary passenger revenues (2105-AE31). These rulemakings were split into two separate rules as they address unrelated matters and splitting these rules apart makes it easier for the public to search for a particular topic embodied by each separate rule. Additionally, any delays in finalizing one issue would not unnecessarily cause a delay in the other. The Consolidated Appropriations Act, 2014 (P.L. 113-76) transferred the powers and duties, functions, authorities and personnel of the Research and Innovative Technology Administration (RITA) to the Office of the Assistant Secretary for Research and Technology (OST-R) in the Office of the Secretary. This rulemaking replaces RIN 2139-AA13.
