Spirit people at the Miami airport tamper with the scales to charge you an overweight fee.
I took a LATAM flight to Miami, my checked bag weighted at 39.5 pounds,
Checked in with spirit, magically, my bag weighted 56 pounds! the rude old woman charged me $125 dollars for a 6 pound overage in weight and guess what? Spirit LOST MY BAG! ON A DIRECT FLIGHT!
After taking their sweet time to find it, they shipped it to me via fedex, the funniest part is that when spirit weight my bag again to create the shipping label, they said it was 40lbs! confirming the old woman at the airport had tampered with the scale!
After finally getting my bag 3 days after arriving in Chicago, I called to get a refund on the overage, and they offered me a THIRTY DOLLAR VOUCHER!
Never flying again with them, it's embarrassing that a company can be so rude and unprofessional.
