Hi,

I'm a long-time Chase Sapphire Reserve (CSR) user but a snail mailing for Delta Skymiles caught my attention so I'm considering the Gold (or maybe Platinum) Delta Skymiles AMEX Card. I have a few questions:
- I assume the free checked bag is valid for European flights also to locations like Italy or The Netherlands? If I travel with a party of 5 on one reservation the bags are free?
- I already have a domestic Delta reservation (booked using CSR points), and it has my Skymiles number linked. Even though this is already booked and 'paid' (using CSR points) will I STILL get the free checked bags for my entire party if I apply for the AMEX Card now?
- I read that you do NOT need to use the AMEX Card to get the free bags, is that correct? (that ties into the question above).

Thanks!
