Maybe they ask more questions depending on how many of your PH days you have used. So if it's your last day on your PH and it's later in the day maybe they ask more questions to make sure someone isn't doing the scam that lulubelle described. If it's the first day of the PH people aren't likely to give their ticket away so it's more likely that the the people who paid for the PH are the ones who want to upgrade. Just a thought since it seems like people are having vastly different experiences. I'm sure it depends on the CM too. Hmmm... OP, you weren't looking extra suspicious that day were you?
