Your experience at LAX will depend a lot upon when you are there. On our return trip from Sydney we arrived at Terminal 5 at around 07:00 AM. We then had an extremely long walk from gate 58A to the customs/immigration area. Customs/immigration was slow but that didn't make any difference because baggage had not even started to arrive when we got to the carousels. When luggage finally started to arrive it took a very long time for our bags to appear. We once we actually had our bags we went through the customs process quite quickly and rechecked our bags without any problem. Then it was back upstairs to go back through security. This time there was a long line which moved very slowly - and didn't move at all for about 10-15 minutes while TSA tried to decide what to do about 3 persons in wheelchairs. Meanwhile I counted 13 uniformed TSA employees standing around talking to each other. The total time to get back through security was about 30 minutes - -which I guess is fast by LAX standards. Much yelling by unhappy TSA employees. Overall a poor experience.
