For second time this week, I'm taking advantage of this benefit. As mentioned above, in LA this week I was allowed one guest free but not allowed a second guest. I'm now sitting in the SF lounge and one guest is complimentary and I can buy a second guest for $59.
It's a nice lounge to wait during my 4 hour layover and a very good perk that Mia wrote just started in October.
I planned to switch to Ink and Ritz for 3x on travel and Chase Lounge/ PP access and get rid of CSR as the new categories cause me more stress than ease. However, I do plan to fly through LA and SF more in the coming years so I might keep card just for the Maple Leaf access. It's be worth keeping it I can use 3-4 times a year (already twice this week) and for the direct flight and hotel booking categories.
