Important Notice

If your journey involves multiple airline partners, please be aware that baggage rules may vary. In case of code-share flights, the carrier performing as the Most Significant Carrier (MSC)** determines the applicable baggage rules. This will generally be the Marketing Carrier, unless that carrier has published a rule stipulating that the Operating Carrier’s baggage policy will apply.

In some cases, the baggage rules applicable to the itinerary may be those of our partner airlines; therefore, passengers may be required to contact their travel agent or our ticketing/reservation agent for further advice.

For itineraries that include travel to or from the United States, or where the journey is subject to U.S. Department of Transportation (US DOT)** regulations, the baggage rules of the first Marketing Carrier on the ticket will apply throughout the journey, in accordance with US DOT requirements. These rules are designed to ensure transparency and consistency for passengers traveling on code-share or interline itineraries involving U.S. points.
