Yes, you can use apps on airplane Wi-Fi, but the specific apps that function depend on the type of Wi-Fi package you use. In 2026, many airlines (like Air Canada and United) offer "Free Messaging" tiers that allow you to use text-based apps such as WhatsApp, iMessage, and Facebook Messenger for free. However, for data-heavy apps like YouTube, Netflix, or Instagram, you typically must purchase a "Streaming" or "Full Access" Wi-Fi pass. Some airlines are now equipping their fleets with Starlink, which provides high-speed, low-latency connection capable of running almost any app, including video conferencing and gaming, just as you would on the ground. It is important to note that even with full Wi-Fi access, Voice over IP (VoIP) calls (like FaceTime or WhatsApp audio) are strictly prohibited on most flights to maintain cabin quiet.
