Delta Comfort fares are booked in "W or S" Class.
Dual character ‘S’ class will still be utilized for Comfort upgrade certificates. Due to a GDS limitation of only being able to display a single class of service, travel agents will see ‘S’ class for all of the following 'S’ class booking options, even though they may be booked as a dual character class of service:
- Revenue (S)
- SkyMiles Award (SN)
- Complimentary Medallion upgrade (SU)
- SkyMiles Global or Regional upgrade (SY)
- eNCI upgrade certificate (SY)

Delta Comfort as an Ancillary Seat Product
Delta customers, including those who purchased tickets via travel agents, can now purchase premium products like Delta Comfort as an add-on purchase for all or part of their journey to further customize their upcoming travel experience – and customers can use a different method of payment than used for the original ticket purchase to do so.
After an upgrade-eligible ticket is purchased, customers or travel agents can go to delta.com or call Delta Reservations to buy Delta Comfort as an add-on, or ancillary purchase, as available – regardless of where the original ticket was purchased. Travel agents may also contact Global Sales Solutions for assistance with an ancillary purchase.
The customer can select a premium product on any individual segment of their journey, or the entire trip, and use the same or a different method of payment for the transaction.
Post Purchase Upgrades
Post purchase upgrades using cash or miles can be done via delta.com. Travel Agencies maintain control of tickets when customers upgrade post-purchase.
Upgrade-eligible tickets and segments must have the following attributes:
- 006 Delta ticket stock
- Segment desiring ancillary upgrade is Delta marketed and Delta operated
- Ticket purchased via fare or SkyMiles award redemption
Some exclusions to upgrade eligibility apply, which include the following:
- Delta Main Basic tickets
- Group PNRs
- PNRs with special service requests for unaccompanied minors, infants or pets-in-cabin
- Origin or destination is Buenos Aires, Argentina (EZE)
Ancillary purchase options are subject to availability and may not be available in all cases for all customers.
Delta Comfort as a Fare Product
Delta Comfort as a fare product is available to view and sell in all major GDS. Delta Comfort fares provide the following benefits:
- Opportunity to use corporate ticket designators and receive associated discounts
- Priority boarding and recognition benefits
- Improved workflow by eliminating the need for separate ticket and ancillary fee transactions
Agency incentives and commissions, as applicable, may be easily applied to Delta Comfort fares. Corporate discounts associated with the fare class (first letter of fare basis code) apply; no need to amend or change existing agreements.
How to Identify Delta Comfort as a Fare Product in a GDS
Delta Comfort fares are available to view and sell in most GDS in the same manner as other fares. Travel agents may view the complete fare rules and details of any Delta Comfort fare available in a GDS fare display.
Delta Comfort fares will use Delta’s Fare Basis Code structure. This structure features a product identifier as part of the fare basis code and allows for unique ticket designators to be applied for discount programs.
Dual-Inventory Check Process
Delta uses a Dual-Inventory Check Process for Delta Comfort fare products. Fares are filed as published fares and the fare basis code will begin with a Delta Main Inventory letter (Q, K, L, U, T, X, V etc.), but the Delta Comfort booking class will always be “W or S” class*.
For the Delta Comfort fare product to be available for purchase, both the FBC booking class and the inventory class of service (W or S) must be available.
Example of a Delta Comfort fare:·
- The identifier in a fare basis code will indicate “C”, “I”, “4” – BLX81PCD
- Booked in W or S class = B fare basis code
- Requires both W or S and B class to be available (dual inventory check)
* Delta “W and S” Class is a valid revenue class of service used for Delta Comfort as a fare. In addition, S class may be used when a customer is upgraded into Delta Comfort or for SkyMiles Award Tickets.
Pricing a Delta Comfort Fare
When booking and pricing a Delta Comfort fare in the GDS, travel agents will need to book a customer’s reservation into ‘W’ or ‘S’ class and use a “price as booked” entry. The lowest available Delta Comfort fare will be offered in ‘W’ or ‘S’ class, if available. Travel agents should not use a “price as lowest fare and rebook” entry to price the itinerary, because the reservation is booked in ‘W’ or ‘S’ class, this entry will rebook the customer into a lower Delta Main fare and remove them from Delta Comfort. If ‘S’ is not available or there are no fares in ‘S’ class, the travel agent should rebook into ‘W’ class which is the higher of the two Delta Comfort fares and use the "price as booked" entry.
Delta Comfort fares are based on dual inventory; both ‘W’ and ‘S’ class, along with the Delta Main class of service are used to determine the fare and must be available for the PNR to price. Delta recommends that travel agents issue the ticket immediately in order to ensure that the PNR prices at the fare quoted.
Delta Comfort Upgrade Certificates
A travel agent must contact Global Sales Solutions (GSS) or Delta Reservations to redeem a Delta Comfort eNCI upgrade certificate. The terms and conditions for these certificates will be changed accordingly. All other upgrade certificates that allow redemption via the GDS will still be permitted.
