Passenger load factor for each flight?
 

Is there anyway to find out which flight of the day has typically the lowest passenger load factor for a certain route by a certain airline?

What you're asking for is propriety and commercially-sensitive information that each airline holds very closely. Basic answer: No.

What about for seasoned flyers out there, usually flights at which period of the day will hv the lowest load factor?

Any specific route or airline you are interested in?

LHR - SIN

oh yea. BA and SIA

Mid week, how is that for an answer. Since we really don't know what the purpose of your question is we can only give you such answers.

I was asked which route and which airline.

The purpose of my question is I want to know which flight should I choose to have a higher chances of having less people on board.

In what class?

The simple answer is no there isn't. Unless you use something like ExpertFlyer to monitor the loads for each flight every day. However, this will only be somewhat accurate as the actual loads won't show, only what fare buckets are available. And you'd need to know the seasonal changes, sales periods, etc which may change the loads. Even then, no way to guarantee a free seat next to you in economy without paying for one.

Sorry, you have to be clearer, because normally people want to know the loads, example, in Y class, that is if the flight is over sold would like an Operational Upgrade because they have status(GOLD etc). I have not had anyone ask which day has minimal loads. Anyway I hope you get your minimal load question answered, so midweek is usually when you get some empty seats in both classes(I am guessing).

What about is there a particular time of a day will there be lower load?

redville, we need to know more, come on.

What class, Economy or Business?

LHR - SIN
Either BA or SIA
BIZ or FIRST/Suite

Good start, now may I suggest you post the SQ question on the Singapore Airlines Forum.

Be specific, especially with month of travel and class.

Now you can then post an identical question in the BA forum, this is the Star Alliance forum and BA and SQ are in 2 separate alliances.

From experience, First class cabins never are full on SQ, I was once the only passenger in 1st on SQ from CAI to SIN.

Now the Business cabins can get full but then again the gurus in the respective forums can help you, perhaps with an estimated response. Now you need to specify the month at least so they have something to work with.

Bon Voyage!!
