Booked a one way LAS to LAX SUV for a week over the holiday period. Sixt Platinum (but through a cc, not actual rentals). Would you guys say I am more likely or less likely (than normal) to get an upgrade? It's not a huge deal, but I'm currently on a refundable rate with Sixt hoping for a shot at a luxury upgrade whereas I could save about $70 off the week if I do a prepaid with Avis. I also have Preferred Plus with Avis (again via cc) but their potential upgrades suck in comparison to what I might get with Sixt.
If the general consensus is that my upgrade chances aren't going to be too great with Sixt, I'll probably wait to see if there's a good Black Friday deal with Avis or switch to their best other offer if not.
