Thank you all for your responses. I have never used Spirit Airlines before and from what I understand, prepaid seat selection is also quite new to Spirit Airlines. I was simply asking if people who have experience with this airline feel that the majority of people choose to submit to extra airline fees, thus rendering it more of a necessity to pay the extra fees to protect the safety of children. Most airlines would not want two year old twins sitting alone!As stated, I have never used this airline, nor is any policy written in Spirit's lengthy passenger bill of rights regarding family seating. Every airline I have ever flown has policies regarding very small children being seated with a parent for safety concerns and comfort of other passengers not traveling with small children. I am guessing if you paid an extra $25 for your premium leather window aisle seat, you would not want to be sitting next to a 2 year old whose parent is 3 rows away!! Obviously, the safety of my children is important to me regardless of $80, which is why I asked the question to begin with! I was not asking for favortism nor was I implying that anyone should personally give up their seat they paid for!! I was simply asking for advice here, as we all know some fees in the travel industry are necessary expenses and some are not as necessary. My question really had nothing to do with character meals, souveniors, or making my kids drink water intead of milk to pay for their seat assignment! I paid Spirit Airlines for 4 seats on the plane. I don't care if I sit in the middle seat in the back row of the plane - I expect the airline to ensure the safety for all passengers above creating extra hidden fees to charge passengers. I understand some people may want to sit in the front of the plane, have more leg room or leather seats and thus pay extra money. Making someone pay for seat assignment so their toddlers will be safe and not a bothersome to other passengers seems more like a form of extortion than a luxury fee, and these fees should be disclosed at the time of purchase. Other airlines fortunately have not adopted such fees. In addition to paying for my plane tickets and luggage, I also paid for my seat assignments, too. Thank you.
