Sounds like what happened to my flight into LAX some 10 years ago, where we had to go around twice because of traffic ahead of us missing their turnoff on the highspeed at that time and had to go down to the 90 degree turn, causing us to go around the first time. And since we were landing the south complex, this meant going around the Palos Verdes Peninsula then back up via Seal Beach.
We turn final, get landing clearance, and have to go around again, because the traffic head of us exited on a closed taxiway, corrected, and went down to the next one, while still on the runway.
Those two cost the pilot and co-pilot a fat bonus because we were 25 minutes ahead of arrival. The go arounds and resequencing put them 10 minutes behind schedule. So I can understand these guys frustration.
