Codeshares: whose plane, whose bags, whose phone number

A codeshare is one flight with two (or more) flight numbers. You might buy one airline’s flight number and board another airline’s aircraft. Search results should show the operator. Policies split: the ticketing airline’s fare rules (changes, miles) versus the operating airline’s aircraft rules (seats, bags at the door, pets, wheelchairs).

Bags and seats

Checked-bag allowances on international itineraries often follow IATA “most significant carrier” logic. At the airport, the first operating carrier’s counter is where you stand. Seat maps on the marketing airline’s app can lag the operator’s map. For paid seats, pay on the site that can actually lock the seat — usually the operator.

Irregular operations

If the flight cancels, the marketing airline that sold the ticket is responsible for rerouting on a single reservation, but the people at the gate work for the operator. Allow extra time and keep both app notifications on.

On Azurovia

We show the itinerary sellers returned. Read the operating carrier before you pick a fare that exists only because of a codeshare you cannot use (for example a pet the operator will not take). We do not operate aircraft.
