Thanks for the comprehensive review. I love reading all the business and first class reviews, but from a practical standpoint its much more useful for me to read about the cabins where I sadly do most of my flying.
I assume most people taking Comfort+ get it as a frequent flyer benefit like us UA folks do with E+? I agree that it doesn't look worth paying a lot extra for.
My other takeaway is that the food looks surprisingly good and plentiful for economy!
