§ 93.223

Slot withdrawal. 

(a) Slots do not represent a property 

right but represent an operating privi-
lege subject to absolute FAA control. 
Slots may be withdrawn at any time to 
fulfill the Department’s operational 
needs, such as providing slots for inter-
national or essential air service oper-
ations or eliminating slots. Before 
withdrawing any slots under this sec-
tion to provide them for international 
operations, essential air services or 
other operational needs, those slots re-
turned under § 93.224 of this part and 
those recalled by the agency under 
§ 93.227 will be allocated. 

(b) Separate slot pools shall be estab-

lished for air carriers and commuter 
operators at each airport. The FAA 
shall assign, by random lottery, with-
drawal priority numbers for the recall 
priority of slots at each airport. Each 
additional permanent slot, if any, will 
be assigned the next higher number for 
air carrier or commuter slots, as appro-
priate, at each airport. Each slot shall 
be assigned a designation consisting of 
the applicable withdrawal priority 
number; the airport code; a code indi-
cating whether the slot is an air car-
rier or commuter operator slot; and the 
time period of the slot. The designation 
shall also indicate, as appropriate, if 
the slot is daily or for certain days of 

the week only; is limited to arrivals or 
departures; is allocated for inter-
national operations or for EAS pur-
poses; and, at Kennedy International 
Airport, is a summer or winter slot. 

(c) Whenever slots must be with-

drawn, they will be withdrawn in ac-
cordance with the priority list estab-
lished under paragraph (b) of this sec-
tion, except: 

(1) Slots obtained in a lottery held 

pursuant to § 93.225 of this part shall be 
subject to withdrawal pursuant to 
paragraph (i) of that section, and 

(2) Slots necessary for international 

and essential air service operations 
shall be exempt from withdrawal for 
use for other international or essential 
air service operations. 

(3) Except as provided in § 93.227(a), 

the FAA shall not withdraw slots held 
at an airport by an air carrier or com-
muter operator holding and operating 
12 or fewer slots at that airport (ex-
cluding slots used for operations de-
scribed in § 93.212(a)(1)), if withdrawal 
would reduce the number of slots held 
below the number of slots operated. 

(4) No slot comprising the guaranteed 

base of slots, as defined in section 
93.318(b), shall be withdrawn for use for 
international operations or for new en-
trants. 

(d) The following withdrawal priority 

rule shall be used to permit application 
of the one-for-one trade provisions for 
international and essential air service 
slots and the slot withdrawal provi-
sions where the slots are needed for 
other than international or essential 
air service operations. If an operator 
has more than one slot in a specific 
time period in which it also has a slot 
being used for international or essen-
tial air service operations, the inter-
national and essential air service slots 
will be considered to be those with the 
lowest withdrawal priority. 

(e) The operator(s) using each slot to 

be withdrawn shall be notified by the 
FAA of the withdrawal and shall cease 
operations using that slot on the date 
indicated in the notice. Generally, the 
FAA will provide at least 30 days after 
notification for the operator to cease 
operations unless exigencies require a 
shorter time period. 

(f) For 24 months following a lottery 

held after June 1, 1991, a slot acquired
