fees. Last year I signed up for the Delta Platinum Card and got like a 80k bonus, unfortunately it came with the $250 fee. When I went to cancel my card I ended up just re-branding to the no-fee Delta Blue card, because I am re-branding I am getting a prorated return of the original fee--it will be only like $20. If I had done it 8 months earlier it would be like $175.
I don't know if this is common knowledge, I didn't know it, and I wish I had re-branded the card about 8 months earlier.
