CAB747 - You are right on all accounts. However, I think as a customer service standpoint, DenverF9Flier has it right that it is annoying to miss part of programs and they can improve on their service.
I could have spoken up and said something and probably should have said something. I'm not inexperienced flyer, have had companion pass on SWA for over 6 or 7 years. Flown just about every domestic airline out there.
It seems to me that the easiest way to accomodate all customers is that at the beginning of the flight they swipe the cards for TV by checking manifest and/or ask for all Classic Plus customers to identify themselves to the FA. I understand the FA are busy people, but this would probably work. Do it before the beverage cart comes out and then there isn't a delay.
As to why I didn't say anything, I can't really tell you, other than I was tired having only had 3 hours sleep. In a way, I was also doing my own test related to the customer service. The money I'd spent isn't huge, but it would have been nice to even see something explained in their in flight magazine. Tell it like it is, and then say if you have one of these fares, let the FA know so that you can be identified as such a customer.
Again, I'm more disappointed in the fact that they don't have a policy/procedure to identify the ClassicPlus customers right from the start.
I do like Frontier as an airline and have even booked family on it for other flights. I just give up the freedom of Southwest Airlines. I had multiple flights covered for free or fare based and knew I could cancel without penalty and use the credits later on. Furthermore, the companion pass can't be beat by any airline credit program that I'm aware exists. Frontier and SWA are by far the premier airlines servicing Denver and beyond. I've been screwed so much by United that I will pay more to avoid using them.
