How would baggage rules be applied on codeshare flights when the flight I booked is operated by a different airline?

On codeshare flights, where the flight you booked is operated by a different airline, baggage rules are generally applied based on the policy of the marketing carrier (the airline from which you purchased the ticket). However, in some cases, the operating carrier's baggage rules might apply. It is essential to check the specific baggage policy details provided during the booking process or contact the customer service of the marketing carrier for clarification. Additionally, you can review the baggage information on both the marketing and operating carriers' websites to ensure you comply with the applicable rules for your entire journey.
