I've flown on numerous Frontier flights and don't find the experience much-different than any other carrier, except for Delta where I have status. Yes, a checked bag is cheaper than a carry-on bag. The discount plan typically only saves about $10 per ticket yet it can be more. But I think the member has to be flying (not positive about that) and then the member plus companions on the res get the lower price. Some people complain that the seating is "harder" but it's not a deal breaker considering the price compared to the competition. And while you can't recline the seat (because they're "pre-reclined" lol), the reality is that the person in front of you can't recline their seat either. Discount or no discount, they can have some amazing prices. I've flown from Orlando to Cleveland for $15ow and to San Diego for $17ow. They have constant sales.
