Downloading Airline Flight Plans

Dear Forum:

I am working on an idea for a research project that involves analyzing a particular or multiple airline flight plans to determine frequencies of a particular aircraft between city-pairs for the next 6 months. I could write a script to find all of the flight schedules through the airline booking website but there may be a better way.

How far out in advance are flight plans scheduled? Perhaps these flight plans will have the information I need?

Any ideas?

Paul

Flight plans are generally filed with ATC approximately 24 hours prior to departure.

I doubt an airline schedule system would contain the ATC flight plan - you need access to an ATC system such as CFMU CHMI or NOP.

Are you simply talking about schedules? This is something different.

After some searching, I found a bit of data that I am looking for. See below:

1) http://www.transtats.bts.gov/
2) Click on "Aviation" on the left
3) Click on "Air Carrier Statistics (Form 41 Traffic)- All Carriers"
4) Click on "Download" under "T-100 Segment (All Carriers)"

This data provides each segment by each airline flying into or within the United States. It lists how many flights an airline flies between each city-pair for a given year. It would be better if the data listed each flight segment but this is pretty good.

The data is limited to flights originating or arriving in the United States. Does anyone know of other data sets outside of the U.S. in the same/similar format?

I'll keep searching and post what I find in case others find this useful.

Paul

Perhaps I was asking for too much information. I'm after the planned schedules. I don't care too much about the planned and actual route taken, just the basic statistics (e.g. planned departure, planned arrival, actual departure, actual arrival, what aircraft was used, how many seats available, etc)

The post I just submitted contains a link to a RITA data set of past flights but not for future flights. It groups flights into each airline and city-pair, which is pretty close to what I'm looking for. The data even provides what aircraft was used, how many flew that route, how many seats were available, etc. The data is a good start but is limited to flights originating or arriving in the United States, and contains data of only past flights, not planned flights in the future.

That's not entirely true - some airlines file with 60-75 min to ETD. All depends on the carrier.

While non-standard, it's not uncommon to file a flight plan within minutes of departure. Usually, though, it's 30-90 minutes.

That's not correct. Most flight plans are filed 90-60 minutes of the departure time.

Ok, so flight plans are not known at least the day of the flight. Two questions:

1) Where is the best place to download/retrieve these filed flight plans?

2) How can I determine how the flight actually went? It's one thing to file the plans and another to fly it according to plan. I understand there are many circumstances that cause a pilot to fly a route other than intended (e.g. weather, traffic, air controller instructions, mechanical troubles, etc).

I figure FlightAware has this information but it doesn't appear to allow me to retrieve other than one-by-one.

Any suggestions would be helpful!

1. Flight aware is good with that on the planned route portion. I got a full route reroute from ATC last night, and flightaware showed the updated route I got from clearance delivery.

2. Again, flightaware shows with fair accuracy the overall path actually taken, but it is not good with showing that compared to the original clearance. Last night, I flew MDW-IAD, and it showed me following the cleared path, but we were subsequently recleared direct to the STAR entry and then again further to a point farther down the STAR.

It is exceedingly rare that I actually fly a flight actually via the original flight plan. Direct clearances, reroutes, and vectors happen on probably 99% of flights.

Flight releases at my company are available around 60 minutes prior to departure for domestic and 90ish for international.
