I have some domestic flights to book in Mexico and indeed looking at the link on the website about allowance, this is what I see:


As an Elite Plus (Platinum), if I read this correctly, it means that if I'm traveling on one of the restricted fares, I don't get any luggage, and the additional luggage information is essentially saying: "Yes, you'll get an extra pieced of the same #, size, and weight as your original fare, which is 0, so you get 0 luggage as an additional benefit". Am I reading this correctly?
