Does anyone who has the Arrival card and has redeemed it for travel expenses know if it has the same loophole the Venture card doe or did ?

With the Venture card you could redeem the same travel expense more than once so you could in effect pay off any balance ( non travel) with points

For example if I spent $100 at a Marriott I was able to redeem points on the Venture Card to pay that same $100 charge multiple times.

This little trick made it much easier to redeem all my Venture points before the AF
