How to check streaming downloads before a trip
Use an offline playback test before relying on downloaded episodes on a flight or train.

Download the specific episodes to the device you will carry and try one in airplane mode. Open the Downloads area rather than searching the regular catalogue. A finished download icon is useful, but a brief offline playback test checks the combination of title, account and device before departure.
Check the missing episode before replacing it
Find the download icon on the individual episode page. Check free space and leave the app open until the download finishes. If a show is missing from the download list, choose an episode the app marks as downloadable. For audio or subtitles, select and test your preferred track while offline.
Plan for a different country or an expiring title
Netflix notes that a downloaded title may become unavailable in another country. Before leaving, inspect any expiry the app displays. Pack an alternative you have also tested offline if the trip depends on entertainment for a child or group.
