A:Answer Hi there Mark, thank you for asking us your questions about the Samsung Galaxy Tab A9+. The Galaxy Tab A9+ will be functional while on an airplane for offline activities, however, to use Wi-Fi for web browsing and email, you will need to purchase in-flight Wi-Fi. You will need an account (like a Google account) to use email and many other features, especially those that require syncing or app downloads. If you think of additional questions for us or if you would like any further assistance, please feel free to contact Support. Thanks for being a loyal Samsung customer. - Debra
