National - upgrade coupons and Emerald Aisle

Just wondering how does a free upgrade coupon work if you are reserving Mid-size car and using Emerald Aisle? Thankyou

Use of upgrade coupon will make your level of service "counter" in my experience. Don't worry about that. Go to the appropriate part of the lot (I assume, full size), pick a car and go to the gate. You could also take any car on the Aisle, I suppose. I do not think that you go to the Exec Selection.

make sense, thanks

One thing that I use it for is if there is a bad selection in EA or ES, with the upgrade, I then have the option to choose from the Full line and still pay the Midsize price. Keeps me from having to justify more to the office!
