Description

Note: In Travelport Apollo System the Air Data Section contains information on PNR segments where the status is Confirmed, Sold, Open, and Waitlisted. The section contains ticketed segments.

In Travelport+ the Air Data Section contains information on segments contained in the Filed Fare, irrespective of segment status. The section may contain ticketed and non-ticketed segments. Where a Booking File has a Passenger with no filed fares, all segments will appear.

For ARNK segments:

Travelport Apollo System ignores ARNK segments

Travelport+:

a) No filed fare, ARNK appears in A04 section. For example:

A0401KL074KLM ROYAL DU etc.
A0402          ARNK

b) With filed fare, all segments included in the filed fare, including ARNK, appear in A04 section. For example:

A0401KL074KLM ROYAL DU etc.
A0402           ARNK
A0403KL074KLM ROYAL DU etc.

c) With filed fare, segment selected (e.g. FQS3), and ARNK not part of the segment select, appears in A05 section. For example:

A0403LK074KLM ROYAL DU etc.
A0501KL074KLM ROYAL DU etc.
A0502         ARNK

d) With filed fare, segment selected (e.g. FQS1.2), and ARNK part of the segment select, appears in A04 section. For example:

A0401KL074KLM ROYAL DU etc.
A0402          ARNK
A0403LM074KLM ROYAL DU etc.

A0504BD235BRITISH MIDL etc.

In Travelport+, the indicator matches the ticket to indicate whether a stopover at the arrival point is permitted.
