航班变更流程

当航变发生时，代理人会收到每个受影响的旅行社PNR 信息。达美航空通过  Delta Messenger fo发送客户通知，PNR会更新，并且在大多数情况下会重新验证票证。OSI备注已添加到PNR中，以便代理人查看有关客票状态的通知 。

请注意： 代理人可能会收到多个航变的通知。 如果需要重新签发机票，不需要在接收到航变通知后立即改签机票。代理人可根据客人的旅行计划以及其自身业务惯例，安排重新换开机票。

重新验证的票证 

通过重新验证机票，达美为代理人保留了票证的控制权。代理人会知道该机票已被重新验证，因为当代理人要求展示票据时，重新验证的数据会被自动包含在内。只要GDS按照正常的行业标准将By revalidating the ticket, Delta preserves agency control of the ticket. The agency will know that the ticket has been revalidated because the revalidation data will automatically be included when the agency requests a ticket display, provided the GDS sends the display request to Delta, following normal industry standards. 

The updated flight, date, time and booking class data, which were changed due to revalidation, on the impacted coupon(s) will display. This information is dynamic (real time), therefore ensuring the agency gets the most current view of the electronic ticket. In addition, it will provide clear indication to the agency that the ticket has been updated and their customer is check-in ready, requiring no reissue by the agency.

• If the itinerary in the PNR and the ETKT data match exactly, the ticket has been revalidated by Delta. No reissue by the travel agency will be necessary. The passenger is check-in ready.
  
  
• If the itinerary in the PNR and the ETKT data do not match, the agency must reissue the ticket using the normal schedule change guidelines (See guideline information below).
  

Please note: It can take up to 72 hours for a ticket to be revalidated once a schedule change occurs. If the ticket has not been revalidated after 72 hours from when the schedule change occurred, travel agents should reissue the ticket as an even exchange to ensure that the passenger is able to check-in for their flight.

Tickets That Are Not Revalidated

Approximately 20% of all schedule changes cannot be updated using Delta’s automated revalidation technology. Below is a list of instances when the original issuing agency must update the PNR, manually reissue the ticket and notify the customer of the changes.

Please note: This is not intended to be a full/complete list; it is only to illustrate the most common conditions where revalidation would not occur.

• There is not a reaccommodation option booked for the customer (ex. UN segment)
  
  
• The minimum connect times are not met with the alternative routing
  
  
• An itinerary that requires a change in the number of flight coupons
  
  
• When there is no E-Ticket in the PNR
  
  
• The new flight option is more than 48 hour later than the previous flight
  
  
• The flight change has caused a misconnection, which requires reaccommodation of the passenger onto other flights, dates or times
  
  
• The itinerary changed from a non-stop to connecting flights
  
  
• Tickets are issued on another carrier’s ticket stock
  
  
• Tickets contain other airline space
  
  
• The PNR contains a 'G' or 'C' header in the name field
  
  
• The PNR contains select SSRs (example: UMNR, PETC, MEDA)

Reaccommodations That Are Not Acceptable

If a customer’s PNR has not been reaccommodated or the reaccommodation provided by Delta is not acceptable to the customer, a Travel Agent may provide alternate reaccommodations using the guidelines from the Schedule Change and Irregular Operations Rebooking Policy for Travel Agency Partners. 

Interline Revalidation Between Delta and Virgin Atlantic

A new interline revalidation program was activated between Delta and Virgin Atlantic (VS) and applies to revalidation transactions.

The interline revalidation program will update the master ticket record in the validating carrier’s system, ensuring that the travel agency-issued ticket will now match the itinerary for the impacted coupon(s), resulting in no reissue required. Travel agents can easily verify the update by displaying the Electronic Ticket Record (ETR) to make sure it matches the itinerary in the PNR.

If the ETR does not match the itinerary in the PNR, Travel Agencies must manually reissue the ticket.

• For DL 006 tickets that include segments operated by VS; if VS revalidates the VS-operated coupon, the revalidation message will be sent to DL and the VS coupon on the DL 006 ticket will be updated to match the revalidation data sent from VS.
  
  
• For VS 932 tickets that include segments operated by DL; if DL revalidates the DL-operated coupon, the revalidation message will be sent to VS and the DL coupon on the VS 932 ticket will be updated to match the revalidation data sent from DL.
