NEWARK, N.J. (CBS/AP) A United flight arriving at Newark Liberty International Airport had to be taken out of service after ants from a carry-on bag appeared in part of the cabin. A passenger on the Venice-to-Newark flight Monday described the scenario in a series of tweets and photos. The guy in front pulls down his case (which btw isnt zipped shut, as middle aisle guy notes to me in an aside) and ants ants ants spill out, running in every which direction, Charlotte Burns tweeted.
