Narrative:

Yesterday at xa:58 was going thru security when a passenger behind me stated; 'why were we late since they are boarding'; in which I replied impossible he must have mistaken us for the cancelled flight from the previous night and they sent the passengers to an unscheduled flight for xa:30 departure. I stated that he must have been slightly delayed since our flight has a xc:00 departure with an xb:00 sign in. When my crew and I arrived at the gate we noticed few people in gate area and many boarding our flight! We were in disbelief since it was not even xb:00 and boarding time was not till xb:15! When we approached the agents they were in shock and did not know how to respond to us. We told them that this was a huge security breach and refused to board until they deplaned all passengers and do another security sweep. They did as requested and we boarded; did our equipment check and were able to board and depart on time.
