Indicates that when paying for a ticket, one can click on "Add Travel Credit", enabling one to use a previous ticket from a cancelled flight. See image:



I do not see this option on the "Review & Pay" page, although the rest of my page looks the same. I'm not seeking guidance on using an e-voucher. I know that is usable under "Other forms of payment". This is not an e-voucher, but rather a travel credit from a previously cancelled ticket.

Do other people see this? Could it be because there are two people in my booking, and the travel credit is only usable by me?

Thanks!
