I will be traveling from NM to TN with a transfer in Denver in June with my 2yr old. I have already gotten the tickets through Frontier Airlines. He will have his own seat and I know he will have to use a car seat. There are certain car seats that are acceptable and I just need to know if the one I just ordered for him is or not. It is: Evenflo - Chase Booster Car Seat, Winchester Style. If any one has a site to recommend or personal experience, please let me know. Please and thank you.
