I put together a tool some time ago for tracking SWUable fares on United. At that time some folks asked me about doing something similar for Delta. The data wasn't particularly easy to get at and I'm generally lazy so I blew it off and didn't think much more about it. Fast forward a couple months and the fare data source I was using dropped offline, forcing me to rethink and re-engineer the whole thing anyways. And while I was at it I discovered that getting the appropriate data for Delta SWUs wasn't so much more work. As such, I'm happy to introduce the Delta SWUable Fares tool. Today is the first day that I've been collecting data so there are a number of rough edges on it, but the basic functionality is mostly working. The map is not functional right now (should be tomorrow) and there is only data for a handful of departure cities so far, but the harvesting tools are running and that should catch up soon enough. If you scroll down past the map you'll see a list of price points, departure cities and destination cities for which you can query data: Pick a city (I chose ATL) and you'll get a list of all the fares, including CPM based on point-to-point distances, from low to high. This also works for destination cities. I used the same list of cities for O/D pairs for the Delta queries as I use for the United ones. It is roughly 5000 pairs but if the one(s) you are looking for aren't listed leave a comment here and I'll add them in. This is very much in the early stages right now so I don't expect it to be perfect. Amongst the improvements that I have on my task list (other than getting the map working) are adding in the alert function that will send you an email based on parameters you can set (e.g. all fares between ATL and ARN or any fares < $2000). I also plan to fix the fare history tracking functionality to watch trends and such. Please give it a look and let me know what you think. Feedback is much appreciated and I'll do what I can to make the tool more useful for the community.
