| Oakland to Las Vegas. I was charged $65 for a carry on, without asking me if my carry on fits their size threshold. At the counter the staff did not even put my carry on in the basket to see if it fits. She saw I have a carry on and she said $65. It did not sound right at all. When I arrived at my destination, I approached the counter asking what happened, the lady took my carry on and placed in in the size basket and it fit right in. She said "why were you charged" I said I do not know. I was given a number to call. My trip was for only 24 hours stay in Vegas for a funeral. The next day when I arrived back to Oakland CA. I approached the same staff at the counter asking why was I charged with out fitting my carry on, She said "sorry sir, we were too busy and hectic". She asked me to speak to her supervisor at downstair departure main counters. I spoke with the supervisor, he fit my beg saw it was fitting. He said to allow him to speak to the employee in the back door inside their office. He came back saying the employee said I had a different bag the day before. I told him that she at her counter just told me she was sorry and she was hectic and mistakenly charged me, and now that I am not before her she says I had a different bag? The manager told me to email customer support to recover the charge. Which I will, and I told him if this to lie to me again, and just to brush me off I will come back to his counter. After emailing back and forth and sending the pictures of my bag inside the carry on fit basket, they said the handle of my beg was slightly higher than the line. They refused to reimburse the charge. I felt completely ripped off. I will never fly Spirit again.
