Here's what happened on my departing flight from BWI. I got to the Spirit area for check-in an hour before my flight. WOW, what a mob of people, 100 maybe 200 people. There wasn't any organization at all, no defined lines except directly in front of the counters or badly identified lines making it difficult to know which line to get in and no one to ask. After choosing a line I got to the counter, only to be told I didn't need to be in line at all and was sent to the kiosk's. After taking a few minutes to figure out what I was doing and going through the kiosk process, it printed out a piece of paper saying I was too late to check in using the kiosk and needed to see an agent at the counter. With the same mob of people trying to get to an agent at a counter and now an agent out among the people trying to direct people to the appropriate line and get the process more organized I still had no idea which line to proceed to. I asked the agent who was trying to organize this total mess and the agent said it was too late for me to get my flight and where I needed to go to rebook. I went and proceeded through that line to an agent and thought ok, not my fault rebook and get another flight. After talking with the agent to rebook my flight, I was told there was a $99 dollar charge to do so. I explained the whole scenario not getting anywhere. I was told customer service was the only way to get the rebooking fee waived. After calling and speaking to customer service, they said no one could waive that fee, I said no one. The agent at the counter said you could. With no way to waive the fee after being told, I could do so I eventually had to pay $99 more than expected for my flight as well as arriving at my destination 17 and a half hours after originally planned. That also affected my budget for the trip. With all this being said I feel I was overcharged the $99 for the fault of the airline check-in process being undefined and very unorganized. I feel I should have been refunded $99 for all of the inconvenience I was put through. I also feel that it is not worth the lower cost of airfare to fly Spirit because of the aggravation that is necessary to get the lower cost. Just pay a little more for a smoother process etc.
