An overnight flight is a commercial airline journey that takes place during the night, allowing passengers to travel long distances while they sleep. These flights typically depart in the evening and arrive at their destination the following morning. They are popular for international travel, as they help travelers maximize their time at the destination by reducing the need for daytime travel. Passengers on an overnight flight often receive amenities such as blankets, pillows, and meals to enhance comfort. Airlines like Delta, United, and American Airlines frequently offer these flights, catering to both business and leisure travelers seeking efficiency in their travel plans.
