Really, other than price, there's nothing good about Spirit. And when you add all those extra charges for everything, the fact that they charge extra for a carry on, or that their bag fees are higher for a lower weight allowance (40 lbs vs 50 lbs for everyone else), the price advantage becomes too small. Other airlines such as JetBlue are much better options.

Likes: price Dislikes: Courteousness, Integrity, Safety (gate agent gave my seat away then blamed me, the security door was closed. She stated that I checked in too late although I had a boarding pass and lied that there were no more seats. Fortunately, an older gate agent was present and took action to print a ticket for me and they reopened the security door. Then they rushed me to get my stuff as I tried to meet the demand. It is clear to me that was indeed happened is that they already calculated the weight as there were additional seats. The problem was resolved and I had an enjoyable flight, but not without unneeded stress.).

Veggie Food was unimaginative and tasteless, and dry. What was that its dish? Whatever it was, it was congealed and unappealing. Apart from Belfast, the movie selection was old.
