You can’t normally sign-up for The Lounge Club, so you need an invite landing page, which is
www.loungeclub.com/inkcard.
( I don't know if u have to have/show your INKCARD to get in )
Enter promo code CHASEINK in the box in the top left.
You will see a confirmation on the enrollment page indicating the free membership and two free entries a year. You’ll then have to sign up and include credit card information so they can charge you if you use the membership for more than two visits. It doesn’t specifically state you need to use your Ink Bold card, but it did only provide Visa/MasterCard options, so they will probably crosscheck to make sure you actually have an Ink Bold card.
Upon enrollment, you and your guest can enjoy access to all participating lounges in the LOUNGE CLUB™ network worldwide. After your first two complimentary visits to participating lounges, a fee of just US$27 per person, per visit will be charged for yourself and any accompanying guest(s).
