01 / IDENTIFIER MAP

British Airways: BA, BAW and 125 are not interchangeable.

Each code answers a different question. The document context is part of the answer.

IATA DESIGNATORBA

Two-character marketing code used before passenger flight numbers, for example BA680.

ICAO DESIGNATORBAW

Three-letter operational designator. The associated callsign shown in operational contexts is “SPEEDBIRD”.

PASSENGER TICKET STOCK125

The first three digits of a 13-digit passenger ticket issued on British Airways stock.

CARGO AWB PREFIXSEPARATE CARRIER

No cargo prefix is asserted in this brief. Do not infer one from the passenger ticket prefix.

SOURCE CHECK Ticket-stock guidance is linked to an airline or IATA source. Identifiers can be reassigned; verify an unfamiliar document before relying on it. British Airways ticket stock guidance

02 / EVIDENCE STACK

Read the offer in the correct order.

  1. 01
    MARKETING CARRIER

    The code printed first.

    A BA-coded flight can still be operated by another airline. Treat the flight number as the commercial label, not final proof of the aircraft operator.

  2. 02
    OPERATING CARRIER

    The airline after “operated by”.

    This line is the decisive clue for the physical flight, onboard product and many day-of-travel processes.

  3. 03
    TICKETING CARRIER

    The contract issuer.

    The ticket number prefix and receipt identify the commercial record that changes and refunds may need to follow.

  4. 04
    FARE FAMILY

    The rule set—not the cabin name.

    Two economy offers can carry different baggage, seat, change and refund conditions. Compare the named fare family on the final payment screen.

03 / CHECKOUT CONTROL

Seven lines to capture before payment.

Save a screenshot or confirmation PDF that visibly includes each item. The record is useful if a seller later presents the itinerary differently.

02Exact “operated by” wording

03Origin and destination airport codes
