Also, make sure that places you normally use a card accept AMEX as many places only accept Visa/MC and do not accept AMEX. All depends on your spending habits.
Of course he should get one or more bonus airline cards! The cash back ones don't have the 20-35K bonus points. Use the bonus ones to fly and cash back for everything else.
I like the SPG with a 25K bonus if you spend 15K. If you can't do the 15K spend, go with the DL Amex. You'll be flying in a few weeks.
