3) In the seats/boarding pass section there is "...... LGBJFK HK 9C NA B ...." or "...... LGBJFK HK 9C N B ...." What does HK, B, and N or NA mean? Obviously 9C is the seat.
4) In remarks, why do some start with H- and others -TBM and others H-/T?
1. HK1 is displayed in the itinerary section of the PNR. As explained by Rasalon it stands for one confirmed seat, opposed to for example HK2 for two confirmed seats or HL1 for one waitlisted seat.
Rasalon's example where it says only HK comes from the seats and boarding pass section of the PNR. Other than in the itinerary section, there is one line for each passenger in the PNR, so no need to append a number after the status code.
The /E at the end of the line means that the flight is eligible for an e-ticket. It says nothing about whether a ticket has already been issued and whether it is electronic or paper.
2. Each phone number in Sabre is preceded by a city code. If the agent does not manually enter a code it will be the agent's home town by default. When booked by a travel agency this will be a valid airport code like LGB if the agency is located in Long Beach. When a PNR is created by an AA agent this field will contain the Sabre internal pseudo code for the reservation office you talked to. QCZ is SWRO RES, AZ.
3. Most of this has been answered by previous posters. B stands for bulkhead.
4. Lines starting with H- are historical remarks. It is always possible to retrieve from the PNR history who entered or deleted them and when. Remarks lines not starting with H- can be deleted and nobody will ever know they were there.
Lines starting with TBM are supposed to contain information where to send a paper ticket to (tickets by mail).
Hope this helps.
