Keeping track of aircraft is hard. Three years ago American Airlines flew the wrong plane to Hawaii. The aircraft they flew wasn’t certified for extended overwater operations. There wasn’t actually anything unsafe about the decision, but it didn’t match the minimum equipment required. The airline simply dispatched the wrong aircraft by mistake.
Now comes word that American kept leased aircraft beyond the expiration date of their agreement according to a lawsuit filed by Wells Fargo in the Southern District of New York.
