Although you’re usually allowed to transport food in an airplane, you are not always authorized to leave the airplane with it. Indeed, some countries (US included) have very strict laws about bringing food across their borders for fear that they may spread plant pests and foreign animal diseases.
Apples, unfortunately for Tadlock who was allegedly unaware of this rule, is one of the food items that are forbidden to cross the US border.
False. I did not enjoy the apple. Instead I received a $500 violation, had my global entry revoked (first time I’ve used it) AND I will be searched on every flight for the rest of my life 🚩#deltaforbiddenfruit #crystaltadlock #delta #applegate pic.twitter.com/ysGfTguppG

After a random search, a US border agent found the fruit in Tadlock’s bag and fined her $500. Tadlock reported her interaction with the agent to Fox 31:
“He [the border agent] had asked me if my trip to France was expensive and I said, ‘Yeah.’ I didn’t really get why he was asking that question, and then he said ‘It’s about to get a lot more expensive after I charge you $500’.”
On top of the fine, Tadlock’s Global Entry status has been revoked. It was the first time she was using it.
Tadlock, who is understandingly frustrated with what happened explains: “It’s really unfortunate someone has to go through that and be treated like a criminal over a piece of fruit.”
Although a healthy alternative to pretzels, it may be time for airlines to stop giving away fruit on international flights. If not, an announcement about the need to leave the fruit on board the aircraft could save travelers from getting hefty fines and a bad reputation with customs.
