I've seen travel agents have the following ability and I'm sure reservation agents have it too: For any particular day and route, they can see what Fare Codes are availabe. so If you say Feb 14th EWR - LHR, they can pull up all flights for that day and see how many V class seats, Y class seats, etc. are available for each flight. So if they know a particular fare sales falls under a V class seat, it's easier for them just to go through a few days and see which days a V class is available and then go on and see the same for a return.... instead of what we have to do - plug in the departure and return date at the same time.</font>
It's an availability checker. There are several of them available on the web.
