1. Use Chrome Incognito, IE private or whatever in Firefox (so AmEx doesn't know it's you) and go here:

2. Choose "Not a Member" (don't worry they'll ask for your Skymiles number again later).

3. A promo page always comes up showing 30K bonus. Don't worry-ignore.

4. Open the personal or biz app- if 50K comes up apply, if not close all out and try again until 50K comes up instead of 30K. Sometimes it takes a few attempts or a different browser but eventually you'll get a 50K app for both personal & biz.

Personals often get instant approvals, biz usually not instant. They email you status link and phone #'s to phone if you want to speed process. (biz is harder to speed).

Free ($1K each, 3mo. spend) 100K Skymiles total plus 2 Club passes each card plus coupons. No fee 1st year.
