Narrative: Right after takeoff; flight Attendants seated in the aft galley area of the 737; called me and told me there was a very loud; ear piercing loud air leak in the aft galley area. They could not determine where it was coming from exactly but it was loud and went away after about 10 minutes after lift off. I informed the Captain and he asked a few questions about where exactly was it coming from; etc. by the time we started our descent; the noise returned; and we advised the pilots again. After landing and passenger deplaning; we asked if a mechanic was going to check the aircraft. The Captain said there was no mechanic at the airport. Now we are asking why he did not inform dispatch about the problem and asked for a mechanic to be called/ flown into ZZZZ? He did not write up the malfunction in the log book........we; all flight attendants; felt ignored and not taken seriously. After talking during our short ground time; the Captain; went to check the aft doors for any debris around the door frame....He also mentioned; that the only thing that had been written up in the logbook; that maybe had 'something to do' with the air leak was a hole on the floor of the cargo hold and had been speed taped. This had been written up in the log book back in September; 2014. Needless to say we; the flight attendants; were shocked.......honestly; we should have walked off the aircraft and refused to take it back. We did not have much time to 'analyze' or decide what we were going to do about the whole situation and went ahead and boarded the plane and on our way home. Again; on takeoff the air leak; ear piercing noise came back. Also; another strange noise was detected. Like a motor running constantly under the galley floor. Flight attendants in the back; described it as like the sound that the flushing motor in the lavs makes; and it was constant throughout the flight. They had heard it before on the previous flight but were not sure and did not mention it to the pilots. We have always been told that we are the 'eyes and ears' for the pilots......... We as flight attendants were undermined and ignored on that first leg. We feel that the Captain decided not to write up the discrepancy in the log book; after that first flight;  so as not to delay his flight back home....... Since they were only doing the turn and going home for the day. We knew there was no mechanic in ZZZZ but we did our part; informed of the high pitched noise (air leak) right as it was happening and expected the Captain to have maintenance check it out at our destination. They could have had a mechanic flown in or so we thought.  There was time to do all that; and ensure that the aircraft was safe to fly home.




Synopsis: B737-800 flight attendants report an air leak in an aft cabin door that makes a loud squeal that increases initially; then stops as the aircraft ascends. The anomaly is reported to the Captain who chooses not to make a logbook entry; due to the lack of maintenance at this airport; much to the reporters chagrin. The return flight is a repeat of the first flight.
