So while we don't have a way explore flights based on say, earn maximum miles per dollar, we do sort by what ee call WisePrice - which actually does factor in the "kickback" you get from miles earned on the flight. We include any elite status or cabin class bonuses too -- and you can value miles at any rate you'd like in your preferences.

Cool! You should mention that somewhere (more) obvious on your website.

Also, please add support for multi-city itineraries.

Yup, I go on lots of "Mile Runs" and it's actually quite difficult to do this with ITA Matrix as-is.

Agreed. I wish ITA had the Google Flights speed and interface for browsing multiple cities and dates but still allowed the advanced routing rules. Unfortunately, I doubt people like us doing MRs are their target audience.

Have they changed it? ITA used to be very popular with the FlyerTalk MR crowd. I used to use it for the searching flights stage (getting info but not booking).

I think the best matrix would be something like OAG, listing all flights that each airline is currently offering, but also listing prices on each flight.

A pipe dream if ever there was one.
