You get what you pay for.
Go to their website. 8 personally prefer SW. You are allowed 2 carry ons & 2 checked bags free and i fly into CVG regularly. When i do ist Allegiant, i prepay my bags and book my flight online. It's much cheaper than waiting til you get to the airport. Go through the entire booking process on their website to see all their extra charges - you don't have to complete the transaction. They charge for your seat, too. And they only fly on and out 2 days a week.
I believe the baggage fee is $25 for carry on not sure about underneath baggage
Not sure about baggage fees. But the issue with Allegiant is the amount of flights they offer. You may get a great rate but they may only fly to your destination 2x a week, meaning if they cancel your flight your next available flight might not even be on the same day. I would only fly with them if your plans are flexible.
Check the airlines website. They would know better then the airport
