I'm curious, how does one gain access to flight schedules/fares? Is this something that anyone can get their hands on and create a service (complexity aside), or do you need some sort of license that costs thousands of dollars? Does each airline have their own way of exporting this data? Is there a single entity that aggregates from all of them? How does the actual data look like? (Is it a dump every X hours, or some…

Fares and rules come from ATPCO ( http://atpco.net ). Flights come from OAG ( http://www.oag.com ). Seat availability requires data directly from the carrier, usually via a live query to the carrier's reservation system. The GDS companies get this data from these sources and then in turn provide (crappy) APIs for customers to use to query it. In general, if you're doing bookings you can get small amounts of the data…

This is what I love about HN. Someone asks a good technical question and literally one of the most qualified people in the world answers it.

> How could not having all that free advertising from flight search engines possibly be a good thing for Southwest? It's not 'free'. See this quora answer for more: ( https://www.quora.com/Why-does-Southwest-choose-not-to-offer... ) Short Answer: It costs money to be there and they can control the variables and environment better on their website. Long Answer: It dates back to Southwest's routes in competing with the…

I'd be very surprised if Google Flights wanted Southwest to pay for inclusion. It already lists Southwest flights with a note "Prices are not available for: Southwest. Flights with unknown prices are at the end of the list." Instead it really sounds like it's Southwest not wanting it to be easy for people to comparison shop. (Disclaimer: I work for Google, on an unrelated project.)

Google hooks into the systems that want Southwest to pay, it's not directly making that decision.

If you don't mind sharing, does ITA/Google Flights still use Common Lisp for the backend?

I don't actually know. But porting it would be a huge undertaking.

I've had the experience of switching from a localized google to google.com/ncr and had ticket prices drop ~4X. I think airlines already try to game the system based on country of origin.

A lot of times, airlines sell tickets based on where the ticket is issued for multiple reasons. If you read some fare rules for these country/region restricted tickets, it'll say something like "valid only when ticket issued in Japan" which leads to people trying to get a flight ticketed on a region specific site of orbitz/expedia/ some-airline .co.jp

Tried this once and found that JAL will not sell tickets to anyone with a middle name. (Presumably due to a bug on their website, where you can only enter given and family name for the ticket, but you have to use your middle name for Secure Flight, and when they don't match, it fails. No combination of putting my middle name in the given or family field worked. Ended up booking an AA codeshare for $55 extra dollars :/)

Bing Travel had predictions for fare fluctuations for air tickets back in 2009. It was pretty awesome back when I flied a lot, but they apparently killed the feature in 2014. Now Google's bringing it back, two years later. I don't understand the future sometimes. ¯\(°_o)/¯

I think they said they killed it because they said they could no longer be accurate with the rate predictions because airlines started limiting data access and it requiring more staff than it was worth. I used it all the time and was sad when they killed it off. I'm sure Google will abandon this project too in 2-3 years like they do everything else that turns out to not be profitable.

30M LoC sounds insane - what is the main reason behind there being so much code?

I almost never use anything other google flights when searching for a ticket. The UI is just so much better and easier to use than the ridiculous bloated crap that most travel sites are (especially when they are trying to shove car-rental and hotel deals in your face). The one drawback is sometimes they are missing local / smaller airlines from their list of flights (which can be a major price difference from the maj…

>I almost never use anything other google flights when searching for a ticket. The UI is just so much better and easier to use than the ridiculous bloated crap that most travel sites are Funny, I was just thinking of how dissapointing the Google UI was: it took me three clicks and two page loads to see where and for how long a layover was. Have you tried Hipmunk[0]? Their interface for flight listings is the best I'v…

Yeah. I've never used Google flights. I always use Hipmunk. Off to check out Google Flights for a trip I'm about to book.

Almost all flight searching / pricing tools have comically bad user interfaces. It's as if the product designers at these companies deliberately went out of their way to limit my options and make me search over and over and over and over. 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 w…

> When's a cheap day to fly to and return from Las Vegas?

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.
