Sec.  93.31  Minimum usage requirement.

    (a) Except as provided in Sec.  93.29 and paragraphs (b) and (c) of 
this section, any Arrival Authorizations not used at least 80 percent of 
the time over a two-month period shall be withdrawn by the FAA.
    (b) Paragraph (a) of this section does not apply to Arrival 
Authorizations obtained under Sec.  93.30 or bought under Sec.  93.27 
during the first 90 days after assignment.
    (c) Paragraph (a) of this section does not apply to Arrival 
Authorizations of U.S. or Canadian air carrier forced by a strike to 
cease operations using those Arrival Authorizations.
    (d) Every U.S. and Canadian air carrier holding Arrival 
Authorizations shall forward in writing to the FAA Slot Administration 
Office in a format specified by the FAA a list of all Arrival 
Authorizations held by the Carrier along with a listing of the Arrival 
Authorizations actually operated for each day of the 2-month reporting 
period within 14 days after the last day of the 2-month reporting period 
beginning January 1 and every 2 months thereafter. The report shall 
identify for each assigned Arrival Authorization the withdrawal priority 
number and half-hour period, the flight number, 3-letter identifier of 
the operating Carrier used for air traffic control communications, 
scheduled time of operation, origin airport, and whether a scheduled 
arrival was actually operated by the Carrier on a specified day. The 
report shall identify any Common Ownership or control of, by, or with 
any other carrier. A senior official of the Carrier shall sign the 
report.
    (e) The Administrator may waive the requirements of paragraph (a) of 
this section in the event of a highly unusual and unpredictable 
condition which is beyond the control of the Carrier and which exists 
for a period of 5 consecutive days or more. Examples of conditions that 
could justify waiver under this paragraph are weather conditions that 
result in the restricted operation of an airport for an extended period 
of time or the grounding of any aircraft type.
    (f) The FAA will treat as used any Arrival Authorization held by a 
carrier on Thanksgiving Day, the Friday following Thanksgiving Day, and 
the period from December 24 through the first Sunday in January.
