In most cases, you can add an extra bag on the airline’s website after you receive your E-ticket. The cost of additional luggage is usually higher at the airport, so we recommend doing it before you check-in, using the carrier’s website or through the carrier’s support line.
Due to some technical issues, the carrier might not offer assistance with adding one or more extra bags to your reservation that was purchased through a Travel Agency. In instances like that, if the fare allows it, you may have the possibility to add the bag directly at the airport.
The airlines can change the policy on luggage fees at any time, so we recommend contacting the airline for the most up-to-date information.
