Yes, Southwest Airlines offers inflight WiFi, and they are currently in the middle of a massive technology upgrade in 2026. Historically, Southwest used an older satellite system, but they are now rolling out Starlink-powered WiFi across their fleet. This new system provides significantly faster speeds, capable of supporting high-definition streaming and gaming. For most passengers, "Internet Access" (for browsing and email) typically costs $8 per flight, though it is frequently free for A-List Preferred members and those on specific fare classes. Even if you don't pay for full internet access, Southwest offers a "free" portal on almost every flight that allows you to use iMessage and WhatsApp (text only) and watch a selection of live TV channels and on-demand movies at no extra cost. By the end of 2026, the majority of the fleet is expected to feature the upgraded Starlink connectivity.
