Synchronization Gap & Married Segments
Link Down & Sychronization Gap
Overview
If there is a Link Down situation or segment synchronization gap, some QR segments can be rejected by UC/US/UN/NO status.
Procedure Description & Illustration
Action Required:
1. Reinstate whether rejected by UC/US/UN/NO and QR office to revalidate e-ticket (irrespective if e-ticket was issued by QR or Travel Agent). For OAL documents, Travel Agent has to liaise with OAL for reissue / revalidation.
2. If you are unable to reinstate ticketed PNRs, please contact local QR office / Contact Centres who will endeavor to get it reinstated.
Requests for assistance with reinstating of such types of PNRS will be rejected if:
1. There is no GK/GL segments visible on the face of the PNR
2. Segments booked using incorrect booking practices
Married Segment Logic
Qatar Airways reservation & inventory system is able to offer, when available, immediate confirmation of flights and booking classes required. This confirmation would be based on availability calculated on Origin & Destination (O&D) logic.
Availability of booking class for particular O&D connection is based on Point of Commencement (POC) decision.
Origin & Destination is considered as continuous journey from point of Origin to point of Destination. Simply, where the passenger begins and ends his or her journey. O&D can be distinguished into three specific scenarios:
- 1 .Local O&D which involves a single nonstop leg (DOH QR DEL).
- 2. Online O&D as a portion of the journey that traverses QR network (IAD QR X/DOH QR BKK). Includes certain code-share itineraries, where QR flight is operated by code-share partner airline.
- 3. Trip O&D is regardless of airlines involved and includes interline segments (ATL DL X/MAD QR X/DOH QR DXB)
When QR segments are sold together in this way or on point-to-point basis (if seats are available on O&D level), they are known as married segments. If segments are married together in PNR, it may not be possible to cancel, price or ticket a segment individually and will be treated as one unit by the GDS/CRS. Marriage Segment Control prevents using flight connections to sell local flights that would not be available if requested outside that connection. QR Revenue Management System (RMS) is capable to identify bypass practices and rejects any cancel request in case the remaining proportion of the O&D is not available. Similarly any bypass of point-to-point sell is detectable by RMS and rejects any onward/inward sell request in case of unavailability of seats on O&D level.
Some variations on the above basic availability controls are possible and are based on individual O&D nature and specification:
- While seamless availability offers equal number of seats available for every booking class and O&D, non-seamless availability calculation, which is very rare, is excluded from such equal seat offer.
- O&Ds constructed from flights with different cabin composition may have booking class mapped between various cabins
- Segments booked with connection more than 23 hours 59 minutes are considered as stopover, hence O&D logic and MSC does not apply.
