I saw that a website was selling status miles on *A during 3 months.
The guy replied to all my questions and told me that this thing worked for other people.
I asked him if the crew would check my membership on the list. He replied : yes, but as he’s giving me a different number with my full name and valid date, I don’t have to be worried. “The card will match the name on the booking so that the airline can verify” (no need for PNR)

should I trust him ? Would my ticket be canceled ?
