I recently transferred within the firm and I am traveling a lot more. People have told me that Delta is the best airline and I have to agree so far.

Which got me thinking. What else am I missing out?

I already got my Amex points, accounts for hotel / rental cars.

Is there a credit card that is great and grants Delta Sky Lounge access? Or other things.

Anything that made your travel easier or perks that I am missing out on.
