@DigitalArk. Do you already have a card with them? I talked with 2 CSRs today and told them I'm thinking of applying for the arrival and asked them about the PC and they said it's not possible.
You're missing the fact that asking a question as an obvious churner is much different than asking the question as an actual cardholder.
I suspect the overwhelming majority of those who applied for the Arrival will request a PC to the no-fee version, once their fee becomes due.
