To watch Netflix offline on a plane in 2026, you must use the "Download" feature within the official Netflix app on a mobile device or tablet before you board. First, ensure you are on a Wi-Fi connection and open the app. Find the show or movie you want to watch and look for the download icon (a downward-pointing arrow). For TV shows, you can often download an entire season or individual episodes. Once the download is complete, you can find your saved content in the "Downloads" or "My Downloads" section of the app. It is important to note that downloads have expiration dates; some expire 48 hours after you first press play, while others last for several weeks. Additionally, you must stay signed in to your account to access your downloads. When you are on the plane, simply switch your device to Airplane Mode, open the Netflix app, and go to your downloads to start watching without an internet connection. This feature is available on most Android, iOS, and Amazon Fire devices, though not all titles in the Netflix library are available for download due to licensing restrictions.
