What means Add-Collect?
“Add-Collect” is a term used in the airline industry to describe the process of collecting additional payment when exchanging a ticket for a different flight. It refers to the difference in fares between the original ticket and the new ticket being issued. If the new ticket is more expensive, the passenger must pay the additional amount (“add”) to cover the difference. If the new ticket is cheaper, the airline may issue a refund for the price difference (“collect”).
