Yes, you can change your device and continue to use the FlyConnect service. On long-haul flights (with A330neo aircraft), you will receive login details after purchase, which you can also use to log in on other devices. You will then be automatically logged out on the original device.
It is also possible to change devices on short- and medium-haul flights (with A320neo or A321neo aircraft). To do this, you must click on "Transfer WiFi" in the FlyConnect portal using your other device and then enter the email address you provided when purchasing the Internet package. Once the system has found your purchased Internet package, you can activate it on the new device. You will then be automatically logged out on the original device.
