When's a cheap day to fly to and return from Las Vegas?
Sorry. Can't answer that, you need to specify the exact
day you want to depart and the exact day you want to come
back, and we might let you look at results + or - 3 days,
unless you don't specify the exact departure airport.
(Disclaimer: I work for Google, on an unrelated project.)
Finally the pricing models are non-intuitive and different airlines have different administrators who all type in their respective pricing slightly differently. To get the the best prices you have to tune each query to the particular style used by the administrator.
Yep. They're pretty clearly designed for the 99% or so case and just (ungracefully) throw their hands in the air for the other 1% or so.
As you say, it's hard to really make the system do the work around finding a cheap flight within a set of parameters.
I've also spent hours booking complicated multi-destination flights, especially in Asia when you need to use multiple carriers. Simply booking as a series of one-way flights can end up costing thousands of dollars more than something more optimized. So you need to end up manually trying various combinations of one-way and round-trip flights and then piecing together the separate itineraries at the end.
This is exactly the problem I have addressed with my flight search tool, Concorde: https://concorde.io/sign-up
Hopper, an app on iOS, has exactly this. You give it a date, and then it gives you a month view with each day color-coded according to how expensive it will be to travel.
It also gives you recommendations about whether to buy a ticket now, or wait until prices go down.
I've bought tickets a few times through Hopper and it worked well. I have no business relationship with them at all--just a happy customer.

These sites all seem to be geared toward business travelers who must travel on particular days from and to particular airports. Anything off that beaten path is an exercise in frustration.
