In looking for good prices for an upcoming trip to Hawaii, I have found that the cheapest rental car price is through Chase Ultimate Rewards (where I would actually pay for the rental and not use any points). My question is that if I book my usual intermediate/mid-size through Chase Ultimate Rewards, will I get my Executive benefits (where I choose my car)? I haven't been able to find this answer, but did find deep in the internet somewhere that when you reserve through Chase, you can not put your loyalty program number and if you call who you reserved the car with they won't add it since it went through Chase. Without my EC number, I don't see how National will see my executive status and let me pick my car. Has anyone experienced reserving through Chase and being able to use Emerald/Executive aisle? Thanks!
