I did everything according to my duties and I slammed the flight door like I usually do except this time I didn't double check it by pulling the door knob. To this point of this event everything was good until we were ascending and all of sudden I see a bright light and I asked the FA C what was that and she said the flight door flew open and I thought I heard the lavatory flew open. So I sat there because we were ascending and very steep at that time. All of a sudden FA C got up and slammed the door closed and sat down quickly. She told me the inside latch was not flipped down. Then I asked again if the flight door was the one that flew opened and C said yes. I told C I was sorry for not getting up immediately when C told me the door flew open. I told C I thought she said the lavatory door flew open and since she didn't immediately get up I assumed it was the lavatory door. The weird thing about this event is that the door closed when usually other times it prevents it from closing. At least that has been my experience.I always double check the flight door but this time I didn't because I slammed it so I assume it was closed; so going forward I will always double check the flight door. I feel C should have gotten up immediately and closed the door when she saw it had opened. I feel pilots should always reminds us to flip the latch down.
B737-700 Flight Attendant reported the cockpit door swung open on initial climb after it was closed on the ground without flipping the latch down.
