Yes, empty or near-empty planes—often called "Ghost Flights"—still fly in 2026 for several regulatory and logistical reasons. The most common reason is the "Use It or Lose It" slot rule; at congested airports like London Heathrow or New York JFK, an airline must operate a certain percentage of its scheduled flights (often 80%) to keep its valuable landing slots for the next season. Additionally, airlines must frequently reposition aircraft—flying a plane empty from one city to another so it is in the right place for its next fully-booked journey. Other "empty" flights occur to meet maintenance requirements or for crew training and licensing. While 2026 environmental groups criticize these flights for their carbon footprint, airlines argue they are necessary for global connectivity and to avoid losing billions in asset value associated with prime airport access.
