My friend has recently had an operation and got a metal pin in her leg. She is allowed to fly however is concerened about the security...will she need to get a doctors note to explain the scars/ beeping at security? And if so where will she have to go for this? Can she just go to normal doctors surgery and get a note? Any help would be much appreciated! We are flying from gatwick with easy jet, has anyone got any experience with this situation?
