Amex plat will pay the fee for global entry, 100 or so for 5 years.

Platinum fee is 450. It gets you in to almost airport clubs around the world, including admirals club, Cathay clubs, and I also believe delta clubs. Priority club good benefit immediately.

No limit. No foreign banking fees also. Rental car insurance...

Lots of other benefits, worth looking into. The airport club benefit rocks, well worth the fee.

Tax deductible business expense.

Very handy and was worth getting in my opinion.

Global Entry Rocks. Online form, 30 minutes. Pay fee. Get approved, do interview with CBP. Also allows with some airlines and some airports, to be in the expedited frequent traveler screening line(US only).
