I believe this is the final month of TAP Victoria’s 10th Anniversary Celebration (same as us here at FFB!!) and this month’s offer is a refer a friend bonus. Earlier in the year you should have joined the program if you weren’t a member yet based on our post that detailed how you can get 100 free miles for joining and if you haven’t you can still earn that bonus (see here) Now they want you to refer friends! The promotion states you have to refer 5 people (at the same time we would guess) and for each one who accepts and joins TAP Portugal’s Victoria program you’ll receive 100 miles. They in turn will receive 500 miles themselves when they join. So for you, if you aren’t a member yet you’ll earn 100 miles for joining and then you refer all your friends as they’ll get 500 miles each while you score 100 more for each of them who join. This offer is available until Dec 31.
