Overview
- International authorities including ICAO, EASA and the FAA still require or recommend switching devices off or using flight mode during flights.
- Airplane mode disables cellular, Wi‑Fi, Bluetooth and NFC, though many devices allow Wi‑Fi or Bluetooth to be turned back on for in‑flight services.
- Since 2022, the EU framework allows carriers to enable mobile calls and data under defined conditions, leaving connectivity choices to each airline.
- Airlines often discourage cellular use to avoid passenger disruption and manage onboard service, a stance also shaped by past FCC concerns about ground-network interference.
- Beyond aviation, using the mode conserves battery, speeds charging, can restore better reception after toggling, and reduces privacy risks from insecure public networks.
