Are aviation OAGs the most reliable source for airline schedules? Or are the actual Airline Timetables themselves the most reliable source in terms of accuracy of flight departure and arrival times at all airports served by the airline?
I'm looking for OAGs for every month, or however frequently issued for 1998 right through until 2005 showing all scheduled flight departures and arrival times for LGW.
Has anyone got any OAGs that cover this period that they would be willing to part with, of which I would be very happy to pay for. Or maybe someone could provide me with the relevant info.

OAG is the most accurate for nearly every airline. The airlines submit schedules to OAG. OAG's schedule covers every single day separately, but online timetables often generalize hiding missing flights on odd days. The only exceptions are airlines like Allegiant that don't seem to care too much about their OAG schedule because they don't sell their flights via websites other than their own.

OAG's definitely have an advantage over individual airline timetables because the frequency of timetables is varied and unreliable. Some airlines don't print them anymore. Some airlines are very religious about it (like every month no matter what) but other airlines are not -- if you find a June 15 2002 timetable and an October 1 timetable, you don't know if the 6/15/02 timetable was accurate through 9/30/02 or if there were intermediate versions. And it's not uncommon for airlines to make changes which are not coordinated with their timetables. Perhaps that 6/15/02 timetable went to press on 6/1/02. The airline could easily make adjustments to their flight schedule after 6/1 which affect things later in summer or early fall -- maybe they decide to reduce a seasonal frequency as of 8/31 instead of waiting until 9/30...and it would never show up in a timetable. Finally, you might miss some airlines by not knowing they flew to LGW for a time. The OAG shows virtually everybody, including some who don't sell in normal global distriburtion platforms. Being a US guy I'm not 100% certain about the scheduled holiday airlines that might have served LGW about appearing in OAG or not, so do be careful about that. But the OAG Is really your best bet.
OAG's are monthly (some versions were actually twice monthly in the past but I don't know if that's still true) and are usually very accurate. The problem for you is that it will likely be very difficult to obtain the dozens of OAG's for such a long period. People who collect them are not likely to just give them away. Some people sell them on ebay or similar places but it would be rather expensive and you might only find some. And people who don't save or sell them have long since thrown them away. Even if you do find someone who has all these who is willing to lend or give them to you, it would be a pricey thing to get them to you because of their bulk.
Years back I got an OAG "electronic version" on disks in a trial offer, and so it is possible that perhaps this could exist for your time period. My concern about this, though, is that even if it does exist you might run into the same issue where most people threw obsolete ones away, and people who did keep them all this time are not willing to give them away. Ccollectors of stuff like this tend to be more into the physical, tactile aspect of it than just the information, and I've never seen anyone selling OAG disks -- only hard copy. It's kind of like the market for collectable timetables. There doesn't seem to be any active market for people selling photopies of old timetables, even though a photocopy could contain all the same information as the real timetable does.
In my opinion, you have a couple of options:
(1) If you are looking for things like numbers of flights, numbers of passengers, what airlines flew, etc, you *may* be able to find data like that in some online database. Here in the states there are online stas for US carriers with that kind of information, but I don't know about the UK. If you are looking for things like specific flight times (like, say, you're working on a project on noise around LGW and it matters very much what time flights are scheduled for ) those type of stats might well not have it.
(2) You could settle for sampling in the period by obtaining certain OAG's, like trying to get a July and a January version for each month of your period. Definitely not as accurate as obtaining every one, but it might be a more realistic goal.
If you want, I could provide a monthly breakdown for LGW for your stated years by destination, number of seats or weekly frequency, airline, aircraft... ? It only takes a few secs to get a year's worth of data. Send me your email via PM if interested.

Quoting JosephJarvis (Reply 3): Would you be willing to take a look to see if your OAG electronic version on your disks do have the information I require please?
Unfortunately I don't have them anymore.
Quoting RJNUT (Reply 5): i get the American Express Skyguide , as they print Allegiant's schedule.
Same here, and they do include just about everything they can including stuff not for sale in the normal GDS systems. Ultimate JetCharter's scheduled flights from Columbus IN to Detroit Willow Run are even in there. Don't know if the OAG includes them or not.

Quoting enilria (Reply 7): Are we talking about the printed ones or their apps/online products? Anything printed is going to be inaccurate as the airlines change schedules constantly. I'd still say OAG is better.
But does he have any hope of getting electronic information from 1998 through 2005?
And indeed while the printed versions cannot be as frequently updated as the electronic versions are, are the updates which airlines continually make usually effective within printed version press time? If on June 18th an airline makes a schedule change effective August 5th, it obviously icannot be accurate in the June printed OAG, and may be too late for the July printed OAG. But as long as it makes the August printed version, it's accurately captured for this purpose.
Might all be a moot point if there's no electronic access for a historic period like this, however.

Quoting knope2001 (Reply 10): Wow...so is that a place the OP could go for detailed schedule information from, say, October 1999? I think he's looking for more than just consolidated stats but true detail.
It offers 38 different search criteria, including the usual (seats, frequencies, operators, flight numbers, times, aircraft) to ASMs, available payload, start/end dates, seat configurations, fare classes, etc., etc., for one specific day, week, month, year, or period of days, weeks, months or years, and per airport, city-pair, or route. Already in contact with the OP, so we shall see if I can assist.

The North American edition (flights within Canada/USA mainly) used to be twice-monthly and the Worldwide OAG (all other routes) was monthly. All paper schedules, including the OAGs, are never going to be totally accurate as airlines are making hundreds of changes every day. To get those changes as they happen you need online electronic access which is expensive.

I remember subscribing to OAG in a federal government agency. I want to say it was around 1996 and OAG was the greatest thing since sliced bread. It was the new kid on the block and in CD ROM format. The first version I remember was paper books and thereafter on five discs which had to be interchanged depending on the data you needed. OAG even provided the monitor. Its predecessor or at least what we had access to was micro-fish format.
We cancelled our subscription after 4-5 years as the internet was slowly catching up. A few airports including BNA www.flybna.com offer an OAG timetable on their web URL
As a travel manager I remember asking flyers to bring back airline timetables which were available at the gate or on the aircraft itself and valid for three or so months. My role was a little easier as a federal agency; travelers for the most part had to abide by the federal GSA city pairs contracts.
Man can be taken from Alaska. Alaska can never be taken from the man.
You can subscribe to the OAG's online schedule product (OAG Flights) for consumers (something over $200 a year) but it only contains current schedules so wouldn't be useful for your purposes. http://www.oagtravel.com/
And with so many free sources of current schedules on the Internet I don't see any need to pay for it.

As your inquiry comes from the UK, you may want to also look for a comparable publication to the OAG, that was printed in the UK. It was called the ABC World Airways Guide. This publication eventually ceased, but I am not sure when exactly this occurred. Just an alternative source to add to the other recommendations. Good luck.
Update. Just researched...The ABC and OAG publications were merged in 1996, so for your dates, this will not be an option. Sorry
