Yes, in general, you can charge your phone on an airplane. Modern airplanes often have power outlets or USB ports at the seats, where you can charge your phone or other electronic devices. This can be convenient during long flights to ensure your phone has enough battery.

However, it's important to note that not all airplanes have power outlets or USB ports, and even if they are available, the specifications can vary depending on the airline and the type of aircraft. Therefore, it is wise to check the airline's website or contact customer service prior to your flight to see if charging options are available on your specific flight.
