How to know how full is my flight?

Mon Oct 16, 2017 7:41 pm

Hi,
a few years ago, I used many times a website which indicated how many seats were available on flights, but I don't remember this website?!

Thanks

You are probably thinking of Expertflyer. That website tells you how many seats (0 to >9) in each booking class (Y, W, B, S, O etc) an airline is willing to sell. In order to use that you will have to know which fare classes correspond to each class of service. When using expertflyer you have to remember that it does not tell you the actual load, only how many more tickets in each fare class the airline is willing to sell. While load factor and fare class availability normally are closely connected, there are exceptions for a number of reasons.

There was also seatcounter.com that did the same things. That's the one I used to use. But it's long gone now :(

Unfortunately expertflyer is not free. However when you sign up the first time you get to use their tools for 5 days without any obligations to subscribe to their service.

Some free booking sites like Travelocity or Orbitz allows you to view the seat chart before booking.
While not an exact science, it would give you a general indication.
Just because I stopped arguing, doesn't mean I think you are right. It just means I gave up!

This site should give you what you need. It's not that user friendly, but it does the job.

This is interesting, thanks for sharing! I was a bit skeptical so I did a quick test and cross-referenced this site with the internal payload info for my airline and here's the results.

First off, You need to know your classes, it'll show a plethora of different class codes from A-Z, you need to find out which airline uses what class code and eliminate all the others. My airline has a 2 class layout, Y and J. So I only focus on those 2 to get my answers, everything else is irrelevant. Also if there are more than 9 open seats it won't show a total, it'll just say 9 so you won't have an accurate total, there could be 9 or there could be 100 open seats.

My sample was 15 different flights over the span of the next 6 days.
6/15 were 100% correct.
3/15 were accurate to within +- 5 seats between Y and J.
The other 6 were flights that had more than 9 opens seats, therefore they just read 9's across the board.

I also checked a few other airlines in Canada, namely Westjet and Porter and all I got was straight 7's across the board for all flights. I guess it only works for certain airlines... I would definitely take these with a grain of salt.

The max number of seats displayed depends on what reservation system an airline uses. Sabre only displays up to seven, therefore airlines that use Sabre (e.g. WestJet) will show as having seven seats available whenever there are seven or more seats in that particular class.

This is likely either one of two things - there can be a lag in availability between an airline's internal reservation system vs. the global distribution systems, which is likely where this tool is pulling from. There could also be lag between when this tool refreshes data from the GDS. If you're using seats on aircraft minus actual load data to check, keep in mind this tool will show seats still available for sale, so if your airline is overbooking the available seats will be seats left + allowed oversales.

With most airlines, you can actually gain some info using the other classes. Even if two flights are showing Y9 or Y7, if the lower economy buckets - they vary by airline, but they seem to appear below Y on this tool - are closing up on on one flight, there are likely fewer seats left on that flight than on the flight where availability is 9 or 7 down the board.
