Just got my Venture X Card- Set up my prioity pass membership and Hertz President Circle as I have flights and car rental booked next week. I was reading the guide and it mentioned coverage for previous travel purcahses. You can make travel purchases directly from any travel provider using the rewards card account and reedem your miles to receive and account credit within 90 days. Car rental wil be around $300 in 2 weeks and if I can charge the $4000 I need to get the 75,000 mile bonus within 90 days can this apply?
Is it a flat one to one redemption- so a $300 charge should cost me 30,000 miles?

Any other quirks of this card I should know compared to a Chase Sapphire Reserve Card? I did figure out the restaurants do not work on priority pass.
