# Codeshare

Codeshare means one airline markets a flight that is operated by another airline, which can affect display and servicing rules.

Codeshare is an airline arrangement where one carrier markets a flight under
its own code while another carrier operates the aircraft. The traveller may buy
from the marketing airline, but the operating airline delivers the flight. This
distinction matters for display, eligibility, servicing, and traveller
expectations.

## What codeshare means

A codeshare flight has two roles. The marketing carrier presents and sells the
flight under its code. The operating carrier provides the aircraft and crew.
Both roles can be visible in a booking path, and both can matter later.

The point of codeshare is network reach. It lets airlines sell journeys beyond
their own operated flights, often as part of wider commercial partnerships. For
sellers, the task is to make the operating carrier clear enough that the
traveller understands who will actually fly the service.

## Why the distinction matters

The marketing carrier may shape the offer, but the operating carrier may govern
some onboard or airport rules. That can affect seat characteristics, service
availability, check-in guidance, and disruption handling.

Codeshare is therefore more than a label in a flight number. It changes how
information should be displayed and how post-booking questions are routed. A
clear seller shows the relationship without making the traveller decode airline
terminology.

## Commercial impact

Codeshare can improve choice and coverage, especially on itineraries that cross
regions or connect networks. It can also add friction if paid options are shown
without enough context.

For merchandising, the safest approach is to respect the operating carrier's
rules and present the option in plain language.
