> Thank you for building ITA Matrix - it is amazing tool and I don't know what I would do without it.

Honest question (I swear I'm not trying to troll): what do you actually do with it that you can't do (or do as well as) with Google Flights or Kayak or some other site like that?

I ask because I've used ITA Matrix and never managed to find a cheaper flight than I can through "normal" means... but I rarely fly multi-destination (and basically never do more complicated stuff) so I'm not sure if the use case is beyond mine or if I just don't know how to utilize it in a useful manner.

- Time bars (incredibly handy for optimising for things like tight connections, which can be essential when flying international and missing a connection means being stranded for a day): https://i.imgur.com/RteViUF.png

- Multiple departure/destination airports (you can search SFO,SJC,OAK to LGB,LAX,SNA and back in a single search). To be fair Google supports this on desktop too (but doesn't on mobile).

- Better search for return flights with variable stay lengths (Google only does a 5x5 matrix, ITA Matrix does a full month).

However, perhaps the biggest downside is that you can't actually book through ITA Matrix. It only finds the fare, you have to find it elsewhere to actually buy it (although Hipmunk takes routing codes, which makes it easier)

One of the features I like to use a lot is the ability to specify fair classes. As an example, say I want to fly to Tokyo, and I am an Alaska Airlines mileage plan member. Alaska Airlines does not fly to Tokyo, but it has deals with airlines that do. However, sometimes the fare classes are quite complicated. For instance, "Economy" is broken down into many buckets, and not all are created equal. For instance, Delta has at least 13 buckets for Economy, and they each 'fare class' award different amounts of mileage to Alaska flyers [1]:

E: 25% Mileage

L, U, T, X, V: 50% Mileage

H, Q, K: 75%

B, M, S: 100% Mileage

Y: 125% Mileage

If you search on Google Flights, these will all be called "Economy". If you search on most of the other OTA's, you can sometimes find the fare class during checkout or even as part of your search results, but you can't filter on it (Hipmunk is one that does support some of ITA's syntax for these filters, but not all). The buckets aren't always strictly more/less expensive, but they're usually not exposed very easily, if at all[2]. So, you're often left crawling from listing to listing, expanding to see if they are going to get you any miles. (I'll save the debate of whether miles are worth all the effort for another day.)

On ITA, it's not unreasonable to construct a query that says "During the month of November, show me round trips that are between 12 and 19 days that are going from Denver to either Narita or Haneda Airports, which will earn me more than 50% miles on either Delta or American or JAL, but also only ones that connect in Portland or Los Angeles, with no prop planes or overnight stops, and no <50 minute connections or 3+ hour connections". (I wouldn't actually specify all of these stipulations, but they're good for the example! :) )

[2] Delta, to its credit, does allow you to search by minimum fair class on its advanced search)

Using ITA Matrix is pretty easy. Using ITA Matrix to actually find better deals takes a lot of knowledge about how the airline systems work.

If you're only looking at flights out of a particular airport and with a specific (default) routing, you'll probably not find anything better.

If you know that certain airports are hubs, or that a particular carrier has a slightly longer route that takes you via a certain city and maybe have a longer layover then you might be able to find some really good deals.

Being in Australia, I really don't get to take advantage of these things at all.

1. there's minconnect -- I can structure flights so I have time to sleep while in transit. You will never find those in a normal search engine, they try to achieve minimal time. There's also padconnect, if you don't like booking right on MCT -- which is often wise! -- then, as the name suggests, this will add N minutes to the prescribed minimal connection time.

2. As recently revealed by the company http://www.flyertalk.com/forum/27265924-post483.html you can avoid connections in certain countries which can be beneficial for visa purposes or certain personal privacy requirements ( I know a German physics professor who refuses to go to the US because of the fingerprinting. )

ITA Matrix Powers Google Flights and Kayak, or at least parts therein.

Last time I tried I found the fact I was able to select multiple departure airports and multiple destinations and see a calendar of fares a great way to find the cheapest fares.
