Sounds like you outgrew it. Neither of my Cap Ones has an AF, so I've just SD'ed them for now. My QS is my second oldest active CC, but I haven't used it in a few months. I don't think I've used my Sony Card in over 3 years.
Yes. That's probably the main perk though. Status upgrade. Also, if you stay at a Hilton a lot, you can double dip acquiring points. Hotel and card.
What do you mean by double dip?
Get points from Hilton for staying and points from Amex for staying.
