Initial Delay Codes (00X to 89A, including 97A to 99A) are to be assigned to the first flight delayed for a particular reason(s). If more than one Initial Delay Code is assigned to properly document the reasons for a flight delay the Initial Delay Code with the longest delay (in minutes) is to be listed first and will be considered the primary delay reason for the flight. Any flights delayed due to the impact of a previously delayed flight are to receive the corresponding Reactionary Delay Code (92A to 96A) associated with the Initial Delay that impacted the previous flight(s). A listing of the correct Reactionary Delay Code associated with each Initial Delay Code is provided in the Reactionary Delay code column adjacent to each initial delay code. If more than one Reactionary Delay Code is assigned to properly document the reasons for the flight delay the Reactionary Delay Code with the longest delay (in minutes) is to be listed first Additional delays experienced on a flight delayed for reactionary reasons should have the proper Initial Delay Code added after the appropriate Reactionary Delay Code(s) in order to account for the station delay above the Minimum Standard Turn (MST) time. Delay Codes Rev.: 02 • 18-Nov-21 Uncontrolled Copy When Downloaded or Printed Page 5 of 7 Delay Codes Arrival Delay Codes ( For use in Amazon Operations Only) Arrival delay codes will only be applied to flights operated for Amazon Prime Air. Codes may be either carrier controllable (delay codes ending with the character “C”) or non-carrier controllable (delay codes ending with the character “U”) and must be assigned when a flight arrives after the STA. Carrier controllable delays indicate an item that is a responsibility of Silver Airways as agreed with Amazon in the Air Transportation Services Agreement (ATSA), while non-carrier, or uncontrollable delays, indicate an item that is a responsibility of Amazon as agreed in the ATSA. The arrival delay should correlate with the assigned departure delay if a departure delay is assigned to the flight.
