When booking a flight:
If baggage is included, you’ll see a baggage icon next to the fare price.
If there’s no icon, baggage is not included unless clearly stated otherwise.
Whether baggage is included depends on the fare type offered by the airline.
Some airlines let you add baggage during the online booking process.
If you can’t add baggage online:
After booking, log in to the airline’s website to add baggage where possible.
If that isn't possible due to a code-share or other restrictions, you will need to add baggage at the airport — this may incur additional fees.
