You can watch Netflix on international flights, but it requires some preparation as in-flight Wi-Fi is often too slow or expensive for reliable streaming. The most effective way is to use the Netflix "Downloads" feature on your smartphone or tablet before you leave for the airport. This allows you to store movies and TV shows directly on your device, which can then be played in "Airplane Mode" without any internet connection. In 2026, while more airlines (like Air Canada and Delta) are rolling out high-speed, streaming-quality Wi-Fi on long-haul international routes, many still block high-bandwidth services like Netflix to preserve the connection for other passengers. To ensure a smooth experience, always check the expiration date of your downloads, as some titles only remain available for 48 hours once you start watching, and remember to pack a portable power bank, as continuous video playback can drain your battery rapidly.
