Thanks to everyone who provided feedback. I am aware of the extra fees. Decided not to pay for seats, this is what I do on Spirit and it always works out fine for us. We are packing only a personal item. I ordered 18x14x8 bags on
amazon for $9 each, simply because we are only going for a long weekend. I am hoping Frontier works for us, because the price speaks for sure. I scored $20 each way, plus I needed to be Den member for $50, so for grand total of $170 all three of us are flying to FL nonstop RT. The price was right for sure, I just hope the experience is just as pleasant.
