30mins for post-flight is not uncommon- and that's going as fast as possible. The amount of double handling that goes on is ridiculous. Half the things the CC have to pick up and put away go right back out on the seats again when the cabin dressing team arrives...

Time could definitely be saved there...
One flight last week we boarded the aircraft approx 1hr 40 prior to departure. All crew security, catering and cabin checks were complete 1hr10 prior. We stood around for at least 30mins before boarding commenced, despite giving the go ahead when we were ready. To me it appeared no effort was made to hurry the pax. Eventually the door was closed 10mins after dep time. No cargo doors were open. Love to see what the delay got attributed to. The crew I bet, and not pax boarding after sched departute time...
