Cuban Overflight Permit

Cuban overflight permits are required to fly through Cuban Airspace. However, there are a few airways that do not cross over Cuban territory where transit has been allowed without requiring an overflight permit.

Cuba is NO LONGER giving free overflight permits to light aircraft regardless of MTOW, ownership and purpose of flight. In the past, aircraft with an MTOW below 6,600 lbs, flown for tourism purposes by their owner, could be granted a FREE Cuban Overflight Permit. That exemption is no longer possible under the new rules and ALL aircraft that require Cuban Overflight Permits will be subject to the corresponding permit and airspace fees which must be paid to the Cuban government.

Member and non-member rates for Cuban Overflight Permits:

MTOW From (lbs)

MTOW To (lbs)















MTOW From (lbs)

MTOW To (lbs)















These fees include permit fees, airspace fees, processing and payment fees.


  • We cannot guarantee Cuban Overflight Permits will be obtained if the request is received 48 hours or less prior to your scheduled departure time.

  • Requests for Cuban Overflight Permits made less than 3 business days prior to first flight will be assessed an additional          US$100.00 for rush service

Southern Border Overflight Exemption

When returning to the USA from Mexico or any country south of 30 degrees north, you must make your first landing at a CBP Designated Airport Of Entry (AOE) closest to the point of border or coastline crossing, UNLESS you have a valid Southern Border Overflight Exemption (BOE) and you comply with the requirements of the Exemption.

All General Aviation operators utilizing a BOE must abide by all the applicable requirements and regulations, including:

  • An electronic or paper copy of the BOE letter must be kept on board 
  • The aircraft commander, operator, or authorized representative must still obtain landing rights approval or permission to land directly from the U.S. CBP port of arrival and must provide advance notice of arrival
  • Only approved aircraft capable of complying with regulatory flight behavior requirements may be utilized
  • Operators of exempted aircraft must utilize a transponder that reports aircraft position and altitude (i.e., Mode C, Mode S)
  • Operators of exempted aircraft must fly in accordance with instrument flight rules (IFR)
  • Operators of exempted aircraft must maintain altitudes above 12,500 feet mean sea level (unless otherwise instructed by Federal Aviation Administration controllers

As of June 2018 the Operator can use the BOE with any aircraft and any crewmembers, provided that the operator, aircraft and crewmembers are listed on the eAPIS manifest submitted to CBP for which said BOE is to be used and that the manifest is authorized by DHS.

NOTE: Processing time may take up to 30 days.

Mexico Airspace and ATC Over-Time Fees payment

If you are not landing at a Mexican airport and do fly through Mexican airspace, you will be liable for paying Mexican Airspace fees. If these fees are not paid, your aircraft may be denied entry into Mexican airspace on future flights or seized after landing at a Mexican airport.

The way Mexico's airspace regulations work is drastically different from any other country making it almost impossible for a non-Mexican pilot to comply on their own. What makes Mexico’s regulations unique from other countries are four things:

  1. The regulations are published in Mexico’s tax code, not in their Aeronautical Information Publication (AIP) and therefore do not appear in any international aeronautical publications

  2. Airspace fees are calculated based on the wingspan of the aircraft and NOT on weight

  3. Mexico does not issue an invoice to advise pilots that they have incurred a fee. It is the pilot’s responsibility to correctly determine the amount owed per the regulations

  4. Airspace and over-time fees can only be paid via a Mexican bank

CST Flight Services can help you stay in compliance with the payment of your Mexico Airspace Fees. The procedures are detailed below.

Due to issues with Mexican authorities we cannot make any further inquiries directly on behalf of aircraft owners. However, we can assist you with obtaining the information and the processing of payments.

If during the last 10 years your aircraft made a flight through Mexican airspace that neither took off from, nor landed in, Mexico, you are subject to Mexican airspace fees. Also, any aircraft that landed at a Mexican airport outside of its normal operating hours has incurred an ATC overtime fee which must be paid using the same procedures as airspace fees. 

Mexico Payments for CURRENT Flights

If you wish to make payments to the Mexican government for present flights you must provide your flight history within the first 5 days of the month after the flight took place. 

Submit Flight History and Pay Online

Inquires About Outstanding Fees

The pilot is responsible for determining any amounts owed for Mexican airspace or overtime fees with the Mexican government for flights already made. To do this, the pilot must contact SENEAM offices (Servicios a la Navegación en el Espacio Aéreo Mexicano) directly.

We cannot make any further inquiries directly with Mexican authorities on behalf of aircraft owners. However, we can assist you with obtaining the information you need so that we can process the payments on your behalf.

In order for CST Flight Services to assist you in making the payment, you will first need to determine the amount owed for past flights.

For non members please contact us via e-mail at customersvc@cstflightservices.com

For members. To inquire about airspace fees owed, please download the document below which includes a set of detailed instructions for determining any amounts owed for both Mexican airspace and overtime fees. 

Once SENEAM has provided the information about the overflight(s) for which fees are owed, you will have to e-mail us the document that you received so we can calculate back taxes and international finance fees in order to make the payment on your behalf.

International Permits

Be in compliance… avoid delays, fines or denial of entry into foreign airspace!

Obtaining the required international permits to comply with the overflight and landing regulations of foreign countries can be a complicated process when planning an international trip. Charter Operations may also be subject to additional regulations and requirements on an international trip. If you need assistance in obtaining the required permits, we can help.

With this service we obtain the required international permits, but you take of everything on the ground at the foreign airport:

  • Payment of Airspace fees
  • APIS filing, when requested (1)
  • Entry/Circulation Permits for flying within a country where required (1)
  • USA CBP Southern Border Overflight Exemption (BOE) allowing you to overfly the 32 Designated
  • CBP Airports to a more convenient CBP airport when entering the US on a flight from a country “south” of the US (2)
  • Foreign Charter Operating Permits

(1) May not be possible in certain countries if not using our Ground Handling Service

(2) May take up to 30 days to obtain

Airspace Fees

Most countries –including the U.S.- charge for the use of their airspace and ATC services. The regulations and methods for determining how much is owed, and how to pay it, vary from country to country.

Important facts to be aware of:

  • Some countries waive the airspace fees if your flight originated, or ended, at an airport in their country, whereas others charge regardless.
  • Some countries will send an invoice; some do not.
  • The currency and payment procedures vary by country, and some can be difficult to comply with.
  • Unpaid airspace fees can accrue delinquency fees, growing over time.
  • Aircraft with unpaid fees may be denied entry into airspace or detained upon arrival in a foreign country.
  • Regulations and procedures vary and can change at any time.

When purchasing a used aircraft, make sure that you are not also purchasing the unpaid airspace fee liabilities of that aircraft. Most foreign countries assess the debts to the aircraft, not the operator. With our Airspace Fee services, we determine what you owe and get it paid for you.

If you think you may be liable for unpaid airspace fees for routes of flight through COCESNA, COLOMBIA, CURACAO, JAMAICA, MEXICO, PANAMA or PIARCO airspaces or if you receive an invoice for airspace fees owed and would like our assistance to:

  1. Inquire about any unpaid airspace fees owed for your tail number, and/or

  2. Make payment of airspace fees owed on your behalf

Please contact us by e-mail at customersvc@cstflightservices.com

A few notes on Mexico’s APIS requirement

  • APIS is mandatory as of January 1, 2014
  • A Mexican APIS must be filed with Mexican Immigration for flights TO and FROM Mexico. Fines range for US$ 5,000 to US$ 50,000 for non-compliance
  • A process for filing a Mexican APIS for PRIVATE General Aviation flights is now available that DOES NOT require the use of a third party portal
  • The timing requirements for when manifests have to be filed have been modified to make it easier to comply within a more reasonable time frame (First APIS submission can be made within 24 hours prior to departure; the second submission must be made 30 minutes prior to departure)
  • The new procedure establishes that a manifest must be filed by completing the approved Excel spreadsheet provided by Mexican Immigration. For more information on the procedure for filing Mexico APIS, please  click here
