I've sometimes read that turnaround times have/can become deciding issues for an air carrier to choose (or not) a type of plane. Who specifies the turnaround time for a given type of aircraft? The manufacturer? The operator? What factors determine the turnaround? At which point does the turnaround time begin to count: at the moment of landing or when the doors have been opened?
Any comments on the subject will be most welcome, as well as specific info on the following types: 717-200, 737-600, 757-200 and 777-200. It goes without saying that data on other types is just as welcome.

There has been a number of discussions on this subject on this forum.
The fastest I know of is around 20 minutes for 124 passengers, which is the time allotted by Southwest Airlines (WN) to turn around their 737-300 and 737-700 planes. My guess is that both EasyJet (U2) and RyanAir (FR) have not much longer turnaround times, mostly because the European low-cost carriers carry more passengers per plane.
For larger planes, I've heard about 35-40 minutes for a 757-200, about 90 minutes for long-range airliners in the A340-200/300 category, and anywhere between 120 and 180 minutes for a 747 (Virgin Atlantic (VS) allots about 180 minutes to turn around a 747-400).

The clock starts ticking from the moment the a/c is "on chocks" meaning the time it arrives at the gate.
At VS we have 2:30 for a B744, 2:15 for A346 and 2:00 for A343, they are the minimum turnround times that are needed to perform all aspects of the turnround fully. A majority of flights do actually have more time than this, however if the flight is running late we sometimes try and turn the a/c in 90 mins, this means that we will not clean the a/c as fully as in the normal turnround, however to most pax they probably wouldn't be able to tell much difference, but due to the extra security since 11/9 we don't usually manage it in the 90 mins unless the i/b and o/b flights are pretty empty, but any time saved from the minimum is a bonus.
At Bmi, we had 37mins for a B735, 40mins for a B733 and 43 mins for a B734. We got 45mins for an A320, and 50mins for an A321.

What is the turn around time of a long haul aircraft that has arrived back at the base, say a BA 747 at LHR, a LH 747 at FRA, a SQ 747 at SIN? How long before it goes on its next outbound flight? Is that any different from the turnaround at the destination?

I have seen them turn a plane around in as little as 15mins. I was waiting for my outbound CO flight at YVR when I see an 11:45am Air Canada flight set to depart to Anchorage, AK. The plane was late in landing a pulled into the gate around 11:30am and was ready for pushback at 11:40am. When I got home, I looked at Air Canada's' departures from YVR that day, and it showed that this flight took off on time.

From a coordination standpoint in a hub, we track all the flights that may be running behind schedule.
You can't make people disembark any faster than they can physically move. (Although there have been many times I would have loved to provide a little extra assistance).
For instance on a 132 passenger A319, if I have a crew that does not have a flight for another hour, I will assign them to work the late arriving flight so both the forward and aft bins can be simultaneously offloaded. The previously staged outbound bags will be immediately loaded as prescribed by the load planner by the additional crew as well. While this is ongoing, the flight attendants and cabin cleaners are preparing the cabin. Toward the end of the cleaning, the pre-board passengers are brought on board and then general boarding is commenced with the reminder that we are vigilantly attempting to get the aircraft out as quickly as possible.
Passengers usually get the drift. But sometimes......you just can't fix stupid.

Westjet schedules 25-30 minute turns for all 737-200 and 737-700 flights. However, when a flight arrives late, its very normal to see a 15-20 minute turn with 120-140 pax on and off. I've worked on a flight and turned an aircraft in 9 minutes - not heavy mind you, 90 pax on and off. Still something to be proud of though

After being away for an airline for over 8 years, my memory is not totally gone, but here is what I can remember about turn times at the hub station where I worked:
Through flights always had the least amount of time built in their schedules. 737-200 about 20 mins, 727-200 about 25 mins, 757-200 about 30 mins. But, a number of things came into play when it came time to actually work the flight. Some things like cargo loads, fuel loads, mtc. checks, catering, etc. could always cause you to run into a delay. Many times the fuel load was what kept me from making my turn time on a fast turnaround.
Terminating/originating flights had more time. 767-300 about 50 mins. I think this was due to the fact that there were more mtc issues that needed to be addressed at our hub station or perhaps just because it was a terminating flight. Also, more cleaning was done and sometimes the caterers would be pulling more equipment off of a terminating a/c.
But, the biggest variable was the passengers. Even if everybody worked like a well oiled team and could turn a fully loaded 767 in 30 minutes, the passengers would always manage to screw it up. They always wanted to leave on time but when it came to cooperating during the boarding process, they had literally no concept of time. I saw more than one quick turn blown to hell because some self-important business type insisted on carrying on the biggest piece of luggage he could find and board his seat in row 10 when rows 30-40 were being called. And then he would have the nerve to complain that we didn't try hard enough.

AIRLINERS.NET CREW CHAT OPERATOR
Someone once told me the turnaround time on a 737-200 was 7 man hours... so 1 guy can do it in 7 hours, 7 guys in 1, 14 in 30 minutes, notice, this includes all paperwork, passenger unloading and loading, cleaning, baggage, fueling, walkaround, etc...
So counting the normal gate crew for a typical 737 class airliner:
2 Flight crew
3 Flight Attendants
1 ground mechanic
1 "blue tanker"
1-3 cleaners (rare nowadays)
1-3 Customer Service agents (yes i count them too, they do have parts to play)
thats at least 14, yes i realise some of those positions might not be present at all airports, but still its an interesting point...
Also another point, alot of airlines do not do full turns at outstations, instead they double stock the flight at the hub for the return trip. They may also not dump the lavs, take on as much fuel (they will overtank at the hub, depending on weight allowances of course) or do a complete cleaning. This is especially true of regional flights. Whenever i see a Jazz Dash 8 here, 15 minutes is a typical turn, and ive seen it done in less. Engine shutdown, Pax and bags off, fuel, bags on, pax on, paperwork done. Engine Start... no catering, no cleaning besides what the F/A can do in that time. Then again, YYZ-YYB is only a 50 minute flight each way.

For Air France it depends on the station. At some stations, where the aircraft has to tow between arrival and departure terminals, it's longer. Where there is no tow, it's shorter. For example, where I am, we are allowed maximum 2:35 for a 744/A343/777, 2:25 for a 330 (we tow between arrival/departure terminals). These times are from bloc to bloc. So if an aircraft arrives at 15:00, we have until 17:35 to get it back out, otherwise we have to explain why we could not do it within our allowed ground time.
At stations where there is no tow it's somewhere between 1:45/1:55 for "smaller" widebodies (A330/A340) and 2 hours flat for a 777/744.

All our Dash 8 flights in the southern caribbean have a general turnaround time of 15min. Sometimes it is real drama to get the flight out on time. 1 min delay would result in a delay report, something we all try to avoid. We have given some flights 5 min or less turn arounds. Our airport is built in away that we can allow boading passengers to pass the gate and go in the opposite direction to deplaning passengers but they won't mix.
Jets that don't clean and cater get about 30-35 min turnaround. eg JM A320, BW 738.
Narrow body flgihts to the US, turn around in 60min. This includes, cleaning, catering and security inspection, prior to boarding.
Widebody Jets transatlantic, 160-180 mins for flights that clean and cater.

Thanks ever so much to all of you guys for the interesting data you've posted in reply to my question. Fascinating to find out about the little (and not so little) details involved in the turnaround phase. Do feel free to add more if you feel so inclined. I shall be having a look regularly for a while.

I have often wondered this myself. I know that most US carriers and EU carriers who fly across the Atlantic have their aircraft sit for a few hours before turning around and heading back in the other direction. And if I'm not wrong this happens on both ends.
But on the flights to Brazil I've noticed that the flights have the aircraft sitting most of the day in GIG or GRU (for Brazil). Does anybody know if this is because of low traffic or just timing of slots, etc.?
I have flown to Brazil on Transbrasil when they were around and our flight back to JFK from GRU was an all day flight but I also have been on Varig through a night flight. It seems the US carriers only do night flights.
