The Industry Standard for Ancillary Fulfillment
Under International Air Transport Association (IATA) Resolution 725f and Resolution 725g, the Electronic Miscellaneous Document (EMD) is the standard electronic document used to issue, collect payment for, and track airline ancillary services and fees. Just as the Electronic Ticket (e-ticket / ETKT) replaced paper flight coupons under IATA Resolution 722, the EMD completely replaced paper Miscellaneous Charges Orders (MCO), Virtual MCOs (VMCO), and Tour Orders (MPD).
An EMD consists of up to four coupons, matching the standard structural architecture of electronic ticket coupons. Each coupon possesses its own coupon status (such as Open, Checked-in, Flown/Used, Void, or Exchanged) and corresponds to a specific service catalog definition filed via ATPCO (Airline Tariff Publishing Company) and governed by IATA standards.
EMD-A: Associated Electronic Miscellaneous Document
An Associated EMD (EMD-A) is directly linked to a specific flight coupon of an electronic flight ticket. It represents services that are intrinsically tied to flight transport and cannot exist or be consumed independently of that specific flight segment.
Key operational characteristics of EMD-A include:
• Strict coupon-to-coupon linkage: The EMD coupon record stores the associated 13-digit e-ticket number and the specific flight coupon number (e.g., ETKT 1762456789012 coupon 1).
• Automatic coupon status synchronization: When the e-ticket flight coupon status transitions in the airline departure control system (DCS) from 'Open' (O) to 'Airport Control' (A), 'Checked-In' (C), and finally 'Flown' (F), the corresponding EMD-A coupon status updates synchronously.
• Disruption and re-accommodation handling: During involuntary schedule changes or irrops rerouting, the EMD-A coupon is automatically or manually reassociated with the newly protected flight coupon on the operating carrier.
Common service categories fulfilled via EMD-A include:
• Pre-paid excess baggage, extra piece allowances, and heavy/overweight bag fees.
• Advanced seat selection (standard seat fees, extra-legroom seats, bulkhead, and emergency exit rows).
• Pre-ordered paid meal selections.
• Priority boarding, fast-track security, and priority baggage handling tagged to a specific leg.
• Special baggage items such as sporting equipment, musical instruments, and pets in cabin (PETC) or hold (AVIH).
EMD-S: Standalone Electronic Miscellaneous Document
A Standalone EMD (EMD-S) operates independently of a specific flight coupon. While it is created inside a passenger name record (PNR) and may relate to a traveler's general itinerary, it does not require an active flight coupon link for coupon status progression.
Key operational characteristics of EMD-S include:
• Independent coupon lifecycle: The coupon status is updated to 'Used' (F) either manually by an agent, automatically through downstream service consumption at a ground facility, or upon redemption during reissuance.
• Financial and administrative settlement: EMD-S serves as the primary accounting instrument for penalties, deposits, administrative service charges, and non-transportation services.
• Value storage and portability: Residual value vouchers and credit memos stored on EMD-S can be redeemed as a form of payment against future ticket purchases within their validity period (typically one year from issuance).
Common services fulfilled via EMD-S include:
• Ticket reissue penalties and date change fees (when the filing airline mandates collection via EMD rather than an added tax code / penalty box).
• Residual value vouchers (Refundable Balances) generated when a ticket is exchanged for a lower-priced fare.
• Group booking deposits and commitment guarantees.
• Independent airport lounge access passes.
• Unaccompanied Minor (UMNR) handling and supervision fees.
• Name correction administrative processing fees.
Technical Anatomy and Data Standards
Every EMD issued across global distribution systems (Amadeus, Sabre, Travelport) adheres to strict data standards recognized by IATA BSP (Billing and Settlement Plan) and ARC (Airlines Reporting Corporation):
• 13-digit Document Number: Formed by the 3-digit airline ticketing prefix (e.g., 006 for Delta, 016 for United, 176 for Emirates, 065 for Saudia) and a 10-digit sequence number.
• Reason for Issuance Code (RFIC): A single-letter industry standard defining the macro-level service category (such as A for Air Transportation, B for Surface Transportation, C for Baggage, D for Financial Impact, E for Airport Services, F for Merchandise, G for In-flight Services, I for Individual Airline Use).
• Reason for Issuance Sub-Code (RFISC): A three-character alphanumeric sub-code filed by the airline in ATPCO Optional Services, defining the precise micro-service (e.g., '0B5' for pre-paid second checked bag, or '0MJ' for paid extra-legroom seat).
• Present-To / At Location: Indicates the operational venue where the service must be delivered (e.g., airport check-in counter, lounge entrance, or onboard).
• Interline Eligibility Indicator: Flags whether the ancillary document can be honored across interline or codeshare operating partner flights.
Worked Operational Example: EMD-A vs EMD-S
Consider an itinerary for a passenger traveling from London Heathrow (LHR) to Dubai (DXB) on flight EK002 with an economy ticket (ETKT 176-1234567890):
Scenario 1: Purchasing an Extra Legroom Seat (EMD-A)
• Step 1: The travel agent opens the seat map in the GDS, selects seat 24K (RFIC: A, RFISC: 0MJ).
• Step 2: The GDS requests pricing from the airline merchandising engine, returning a fee of 75.00 USD.
• Step 3: An Auxiliary Segment (SVC) is added to the PNR, referencing segment 1.
• Step 4: The agent issues the document. The system creates EMD-A 176-8899001122 coupon 1, associated directly to ETKT 176-1234567890 coupon 1.
• Step 5: At LHR airport, when the passenger checks in, the DCS changes ETKT coupon 1 to status 'C' and EMD-A coupon 1 to status 'C'. Upon boarding, both shift to 'F' (Flown/Used).
Scenario 2: Collecting a Date Change Penalty (EMD-S)
• Step 1: The passenger requests to change the departure date. The fare rule dictates a 150.00 USD penalty collected via EMD.
• Step 2: The agent reissues the flight ticket for the new flight date.
• Step 3: The agent generates an EMD-S for RFIC: D (Financial Impact), RFISC: 993 (Change Fee) for 150.00 USD.
• Step 4: EMD-S 176-3344556677 is issued. It contains no coupon association to a specific flight leg. Its status is automatically set to 'Used' (F) upon successful collection and ticketing settlement.
Market and Airline Variations
• Interline Ancillary Settlement: While multilateral interline e-ticketing (MITA) is universally adopted, interline EMD-A acceptance requires explicit bilateral EMD agreements between operating and marketing carriers. If no bilateral EMD agreement exists, ancillary services must be purchased directly with the operating carrier.
• Penalty Collection Methods: Certain carriers (such as British Airways or Lufthansa Group) allow date change penalties to be processed directly as an added tax or fee (OD tax code or Q-surcharge) on the newly exchanged ticket, whereas other airlines strictly require an EMD-S Reason D document.
• Void and Refund Policies: EMD-A and EMD-S documents can generally be voided within the same sales day (subject to local BSP/ARC settlement cut-off times). Refunds depend on whether the ancillary service is non-refundable by rule (e.g., seat fees often become non-refundable unless the airline cancels the flight involuntarily).
Key takeaways
• EMD-A (Associated) is strictly tied to a specific e-ticket flight coupon number, with coupon statuses updating synchronously through check-in and boarding.
• EMD-S (Standalone) functions independently of individual flight coupons, serving as the standard mechanism for change penalties, residual credit vouchers, and ground-based ancillaries.
• Every EMD coupon requires a 1-character Reason for Issuance Code (RFIC) and a 3-character ATPCO Reason for Issuance Sub-Code (RFISC) to govern accounting and fulfillment.
• Interline fulfillment of EMD-A requires bilateral agreements between operating and marketing carriers; in their absence, ancillaries must be issued directly via operating carrier channels.
