Google Flights runs on some seriously sophisticated algorithms
that scan airline databases in real time. It compares prices from
different airlines and booking sites, sniffing out deals as they pop up.
Search Algorithms and Real-Time Pricing
Google Flights acts as a one-stop search engine
that checks hundreds of airlines and platforms at once. It queries
airline reservation systems and booking sites to grab the freshest fare
data.
Prices update constantly. When you search,
Google pulls live prices straight from airline APIs and third-party
sites, sometimes within seconds.
Results show up in two main tabs: "Best" and "Cheapest".
The "Best" tab tries to balance price with convenience—think flight
duration, layovers, and departure times. "Cheapest" just goes for the
lowest fare, no matter what.
The engine also gives you historical price insights to help you decide when to book. It checks out past trends for your route and tries to guess if now's a good time to buy.
Factors That Influence Flight Prices
A bunch of things can mess with the prices Google Flights shows you. Demand swings matter most—prices shoot up during busy travel times and drop when demand's soft.
Route
competition makes a big difference. If lots of airlines fly the same
route, fares usually drop. If one airline owns the route, expect higher
prices.
Booking timing is another
factor. Airlines release seats and tweak prices at certain
times—searching on Tuesday or Wednesday often turns up better deals,
though it's not a guarantee.
Seasonal trends also play a part. Holidays, summer breaks, or peak seasons for a destination almost always mean higher fares.
Understanding Fare Types and Airline Policies
Different fare categories come with their own quirks, restrictions, and perks that can really change what you end up paying. Airline policies for changes or cancellations can vary a lot depending on which fare you book.
Differences Between Basic Economy, Economy, and Premium
Basic Economy
is the bare-bones ticket with the lowest price. You can't pick your
seat in advance, usually board last, and sometimes you're limited to
just a personal item for carry-on.
Standard Economy gives you advance seat selection and overhead bin access. You can change your ticket for a fee and earn the full stash of frequent flyer miles. Boarding typically happens a little earlier than in basic economy.
Premium Economy
bumps you up to wider seats, more legroom, and priority boarding. You
get better meals, extra baggage, and generally nicer treatment if things
go sideways.
The price gap between basic and
standard economy is usually $30–80 per ticket. Premium economy can run
20–40% more than standard, but it's still a lot cheaper than business
class.
Change and Cancellation Flexibility
Basic Economy Changes:
Most airlines just won't let you change basic economy tickets at all.
If you need to cancel, you'll lose the entire ticket value—no refund, no
credit, nothing.
Economy Flexibility:
With standard economy fares, you can make changes, but you'll pay for
it. Domestic flights usually hit you with fees from $75 to $200.
International
change fees? Those can easily run $200 to $400. If you cancel, at least
you get flight credits, but they're only good for 12 months.
Premium Benefits:
Premium economy and higher fares tend to throw in free same-day changes
or at least lower change fees. Some premium tickets even let you get a
full refund if you cancel within 24 hours of departure, which is pretty
generous.
Honestly, if you're buying basic economy,
travel insurance starts to look a lot more appealing since those tickets
don't budge if your plans do.
