Many airlines offer WiFi onboard flights, but it may not be available on all flights or on all parts of the journey (for example, during takeoff or landing). The availability of WiFi can also vary depending on the airline, the aircraft, and the route.
Some airlines offer free WiFi to all passengers, while others may charge a fee or offer it only to premium cabin passengers. The speed and quality of the WiFi connection can also vary.
In-flight WiFi speeds are not as fast as typical ground-based connections, and may be affected by factors such as the number of users on the network, the location and altitude of the aircraft, and the availability of satellite or ground-based internet connections.
That being said, some airlines are now offering faster and more reliable in-flight WiFi, and the technology is continually improving. Speeds can range from a few Mbps to over 20 Mbps, which can allow for basic web browsing, email, and social media usage, and even some streaming of audio and video content.
It's always a good idea to check with your airline before your flight to find out if WiFi will be available and any associated costs or restrictions. You can also check on the airline's website or mobile app for more information about their in-flight amenities.
