Company Policy; Procedure
We had two jump seaters; one of which was a Flight Attendant. The other jump seater was her friend [and] was NOT a crew member. She didn't work for any airline and was simply just a standby passenger. We did not find out about this until right before takeoff. The Number One FA (Flight Attendant) was looking at the Passenger list to see what airline the jump seater in the back worked for. We thought it was odd that it was not listed. This is when her friend told us that [she] was not a Flight Attendant. We were shocked that the agent let her on. We should have contacted the Captain immediately; yet we did not. I followed the lead of the Number One FA and we took off.The gate agent issued a standby passenger a jump seat. I cannot provide a reason as to why this happened. I know this is a serious and very important safety issue/violation. If I had the chance to do this over again; I would've spoken up immediately and insisted we call the Captain.
An air carrier Flight Attendant reported that a Gate Agent knowingly issued a jump seat to a non-crew; standby passenger who was accompanied by a jump seating Flight Attendant.
