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 rulemaking would also change the way the Department computes mishandled baggage rates from mishandled baggage reports per domestic enplanement to mishandled bags per checked bags. The Consolidated Appropriations Act, 2014 (Pub. 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.
