Just a tip regarding car rentals and was not sure if this info is out there. You book your car rental thru USAA then your trip cancels for whatever reason, and now you want to cancel that rental car. You're charged $50 by the rental company...even if you cancel the rental well in advance, i.e., 24 or more hours. I contacted one of the rental agencies directly and was told that if you "book" thru the mobile app and are prepaying then you're going to get charged the $50 for cancelling. If you "reserve" the vehicle then you're not charged. Pros and cons with booking vs. reserving, mind you. I didn't see an option to reserve on USAA mobile app though. In the end, the rental company took my info over the phone and reserved my vehicle.
