Are you new to the coordination business or not quite familiar with SCR messages? Then, please visit our special tailored" SCR Crash Course"!

Main Principles

Geneva and Zurich are declared "coordinated 'level 3' airports", therefore please carefully study the following information on how to deal with such airports:

  • General and business aviation flights see here
  • Airport slots shall be requested at least 3 working days in advance
  • We only accept SCR formatted messages (Slot Clearance Request) to request, change or delete airport slots (please refrain from calling or sending any ASM, SSM or free-text messages!)
  • We kindly ask you to follow IATA SSIM chapter 6, your cooperation is appreciated!
  • It is mandatory to send all SCR messages in transit/turn-around format using aircraft subtypes only (e.g. 73G or 738 instead of 737). This is applicable for the submission as well as for any later modifications and cancellations (see IATA SSIM manual chapter 6.2)
  • Offers are valid for 3 business days only (IATA WSG chapter 9.13.3) and will be cancelled again if no reply received. Offers issued during out-of-office-hours ("OOH Self Reply") shall be replied as soon as possible.
  • Incorrectly formatted SCR messages are auto-rejected by our coordination system, same applies to retrospective changes!
  • The SSIM chapter 6 formatted message must be plain text (not HTML) placed directly in the email body. No attachments, logos or special characters should be used. The senders email address has to be repeated on the second line of the message header (IATA SSIM chapter 6.2.1).
    Please observe that we do not accept requests sent from free email accounts!
  • An SCR message does not include any provision for ground handling. Please inform your handling agent separately and well in advance!

Actual Day of Operation

A cleared airport slot is valid on the actual day of operation and needs not to be adjusted in case of operational delays (unless otherwise stated). Flights postponed to the next day require a new airport slot and the current slot held must be cancelled. Airport slots for not operated flights must be returned as early as possible.

Note: For General and Business Aviation flights special conditions apply. Please contact directly your handling agent.

Geneva Specials

Any change in aircraft type (including family subtype change) must be advised by SCR. Please mind that on weekends during winter seasons NO upgrade of equipment is accepted!

Zurich Specials

  • Flights into/out of SR Technics Maintenance also obligatory require an airport slot. Requests for such ferry flights must be submitted as single lines (no turnaround format) using service type code "T".
  • World Economic Forum (annual meeting January in Davos):
    Flights in connection with WEF must be cleared via handling agents as several local rules and special conditions apply for such movements.

Historics

  • The SHL will be sent out latest on the respective deadline date and must be acknowledged from your side. Are you missing the SHL after this date contact us immediately!
  • Please mind the "Agreed Historics Deadline" (one week before the submission deadline). Any dispute raised after this date will not be considered!

Submission

  • Any submission (incl. historic submission and submission for historic retiming) must cover at least a period of 5 consecutive movements ("series of slot")!
  • Historical slots cannot be claimed using submission code "N"!
  • Any request must be submitted in turnaround format!
  • Historical arrivals cannot be used to submit new departure requests, same applies for historical departure slots ("historical arrival/departure swaps during submission")!
  • Flight number changes for historic submission must use code "CR" and not code "F"
  • Please submit ad-hoc flights and ad-hoc changes (less than 5 consecutive movements) earliest in February for summer and in September for winter season!

Slot Return

  • Please make sure that your waitlist information does correspond with our records. Without correct information we will not be able to improve waitlisted flights during slot return processing!
  • We kindly ask you to send any non-seasonal administrative changes (aircraft, routing and service type changes) only after slot return processing to ease possible waitlist improvements.
  • Please send any ad-hoc cancellations only after 15th but before 31st to ease seasonal waitlist improvements!
  • We only accept requests for ad-hoc flights (less than 5 consecutive movements) and ad-hoc changes after Historics Baseline Date (HBD)!
  • We require 3-5 working days for the slot return processing and waitlist improvements. During these days we are not able to accept any additional requests or ad-hoc changes for the respective season!
