- Question: In what case doesn't a coupon correspond to a segment?
- Comment: This is getting into the weeds of terminology that most travelers don't need to deal with; there are also sectors and legs and portions and stages and sequences and more, just different ways of dividing up the trip and dividing up the money. – choster Jun 9 at 2:41 (mirror)
I couldn't find the definitions of stages and sequences. What are the definitions of stages and sequences and how do they compare against leg/portion/sector/segment?
Here are the IATA definitions I could find on dividing up the trip and dividing up the money:
|Term Name||Description||Source of Description|
|Coupon||The portion of the Passenger Ticket and Baggage Check or Excess Baggage Ticket that indicates particular places between which the coupon is good for carriage.|
|Leg||The space between two consecutive scheduled stops on any given flight.||IATA,PSCRMe34,CHPT 1,RESO 766|
|Leg||The operation between a departure station and the next arrival station.||IATA,SSIMe38 (2011),CHPT 1.1,RP 1761b|
|Portion||One segment or consecutive segments (even though gap intervenes) via any one Member.||IATA,Reso766|
|Segment||A leg or a group of legs from boarding point of a passenger to a deplaning point on a given flight.||IATA,PSCRMe34,CHPT 1,RESO 766|
|Segment||(Sometimes referred to as City Pair) The operation between board point and any subsequent off point within the same flight.||IATA,SSIMe38 (2011),CHPT 1.1,RP 1761b|
