Flight BE4585 took off just after 4pm for the short flight from Cardiff to Jersey but was forced to run after the lightning strike as a precautionary measure.
The aircraft, a Flybe Embraer E190 G-FBEJ was not believed to have been damaged in the incident but was met with emergency vehicles as a precaution. All passengers were safely disembarked at Cardiff Airport.
Lightning strikes on aircraft are fairly common and pose no significant threat however a direct strike will always result in the aircraft seeking to land as soon as possible to check for any potential damage.
The flight has now been cancelled as a replacement aircraft was not available.
