There are many jokes about Spirit Airlines. The latest incident on the low-cost carrier will definitely be added for those who make fun of the brand. A bat was spotted flying through the cabin 30 minutes into a Wednesday flight to Newark. Several passengers tweeted videos of the scary incident. One person wrote, "Me, twice a year: 'I'll never fly spirit again.' Me, this morning, after deciding I'd rather save 12 dollars." The tweeter continued saying, "I also want to make clear that this bat appeared WHILE WE WERE 30 MINUTES INTO OUR FLIGHT. Where it came from? No idea. Eventually, someone trapped it between a book & a cup and then locked it in one of the restrooms for the remainder of the trip." What was your worst in-flight experience? Did it happen on Spirit?
