When
The airline changed a flight's time or number, or cancelled it: the PNR arrives on a queue with the
old segment (e.g. UN) and the new one (e.g. TK), or a status change.
Steps
| # | Entry | What it does | Why |
|---|---|---|---|
| 1 | QS… on the schedule-change queue (see QT for its name) | Opens the first affected PNR. | |
| 2 | RTA | Shows old (UN/HX) and new (TK/KK) segments. | What changed. |
| 3 | DM2/4 (or DMI) | Checks the connection still meets the MCT. | A later first flight can break the connection. |
| 4 | decide with the client | Accept, or rebook to another flight (SB, SS), or cancel (XE). | The client must agree to a big change. |
| 5 | RF + name, ERK | Accepts: TK/KK → HK; UN/UC/NO → history. | Clean PNR. |
| 6 | TWD | If ticketed: coupons still on the old flight? | Ticket must follow. |
| 7 | revalidate or involuntary reissue | Moves the ticket to the new flight. | See Learn more. |
Check it worked
RTA shows only HK segments; the connection passes DM; TWD coupons match the new flights.
Traps
- Do not just
ERKblindly — check connections and whether the client can still travel. - Big changes usually entitle the client to a free change or refund under the airline's rules (involuntary) — do not charge a penalty.
- The daily schedule file is loaded early morning GMT: work this queue every morning.
