sometimes using almost passive aggressive language. not interested in joining the $9 fare club? you will have to click the button that says no, i don t want to save. for many passengers, every flight seems to get just a little more expensive. spirit airlines tells nbc news when we sell these fares on our website, we are very transparent about what these very low fares provide and what they don t. our bare faerls aour customers to purchase tickets so they can have more money to spend if when they reach the final destinations. i think a lot of people would say, isn t this what you would want from the airlines? to be completely and open and transparent and say, if you re going to choose the cheapest seat in the back of the plane, just beware you may not have the leg room you like or the bin space. these critics say, no, they re trying to shame you into spending more money. ari? yeah. i ll a big carry-on guy. it hits close to home.
