How to Use Google Flights to Find Cheap Flights (Including Flights to Your Cruise)

To use Google Flights to find cheap flights, enter your departure and arrival airports (you can add several of each), open the Date grid or Price graph to see which days are cheapest, then switch to the Cheapest tab and set the bag filter so the fares shown are the ones you would really pay. If you aren’t ready to book, turn on Track prices so Google emails you when the fare changes. When you are ready, book directly with the airline from the booking options list.

This guide covers each of those tools as they work in late 2026. It also covers something most Google Flights guides skip: using the same tools to get to a cruise port, which comes with its own rules about timing, airports and one-way tickets.

How to use Google Flights: the basic search

Google Flights is a search engine, not a travel agent. It compares fares from more than 300 airlines and online travel agencies, then sends you to one of them to buy the ticket. A standard search takes five steps:

1. Choose the trip type. Round trip, one-way or multi-city, from the drop-down at the top left.
2. Set passengers and cabin. Economy, premium economy, business or first. Prices change a lot between cabins, so set this before you compare anything.
3. Enter where you’re flying from and to. You can type a city name (such as “Miami”) to cover every airport there, or add several specific airports to a single search.
4. Pick your dates. The calendar shows the lowest price for each day. Cheaper days are shown in green. Google says these calendar prices refresh about once every 24 hours, so check the live price before you rely on one.
5. Review the results. Use the filters and the Best and Cheapest tabs (covered below), then choose your outbound flight and your return.

Find the cheapest days with the Date grid and Price graph

Run a search, then look just above the results for the Date grid and Price graph buttons. On the mobile app, they sit behind the dates bar.

• Date grid shows a table of fares for different combinations of departure and return dates. Moving the trip one or two days earlier or later often costs much less. Tuesday, Wednesday and Saturday departures are often cheapest on domestic routes, but the grid shows the real pattern for your route.
• Price graph shows the fare over several weeks or months. It’s most useful when your trip length is fixed but the start date isn’t, for example a 7-night cruise with several sailing dates.

Below the results, Google may also add notes such as “Prices are less than usual”, “Prices unlikely to drop” or “Prices likely to increase”. These predictions are based on past fares for similar trips. They are useful as a guide, but Google itself says they are not guaranteed.

Search several airports at once

Searching from more than one airport is among the most effective ways to save money with Google Flights, and many travellers never use it. Click the departure or destination field and add extra airports separated by commas, for example EWR, JFK, LGA, or MIA, FLL, PBI. Results from every airport then appear in one list. Google also has an Airports insight that flags when a nearby airport is cheaper.

Always add the cost of getting from the airport to where you are going. A fare that’s $60 cheaper but lands 70 miles away can cost more once you pay for the ride.

Best vs Cheapest tab: which one to use

Since late 2024, Google Flights results are split into two tabs, and as of 2026 both are still there:

The Cheapest tab can be useful, but look at what it includes before you book. Google says these fares may mean collecting and re-checking your bags between flights, or landing at a different airport in the same city. If you are on separate tickets (also called “self-transfer”) and the first flight is late, the second airline doesn’t have to rebook you. That’s a risk worth thinking about whenever you have something you can’t miss at the end of the trip.

Use filters for bags, stops and airlines

The filter bar above the results lets you narrow the list before you compare prices:

• Stops: nonstop only, one stop or fewer, or any.
• Airlines: include or exclude specific carriers or alliances, which is useful if you collect miles with one of them.
• Bags: add a carry-on or a checked bag, and Google adds the airline’s bag fees to the fares shown. This matters a lot when comparing a basic economy or low-cost fare with a standard fare that includes a bag.
• Times, duration and connecting airports: set limits on departure and arrival times, total travel time, or the airports you’re willing to connect through.

Fares still leave out some fees, such as seat selection and credit card charges, so check the final total on the airline’s checkout page.

Explore the map when you’re flexible

If you know when you want to travel but not where, open Explore from the menu, or leave the destination blank. You will see a map of fares from your home airport. You can set a rough time frame (for example “a week in February”), limit the results to nonstop flights, and zoom into a region such as the Caribbean or Europe.

Google has also added an AI tool called Flight Deals. You describe a trip in plain language, such as “a week somewhere warm in March with nonstop flights”, and it suggests matching fares. It launched in the US, Canada and India in 2025 and was later expanded to many more countries. It is useful for ideas, but for an exact route, a normal search with the Date grid gives you more control.

Track prices and get alerts

When you’re signed in to a Google account, every search shows a Track prices switch. Turn it on and Google emails you when the fare changes noticeably. You have two options:

• Specific dates: watches your exact route and dates. If you pick a particular flight first, you can track that flight alone.
• Any dates: watches the route as a whole and tells you about low fares on dates near the ones you searched.

Your tracked flights appear on the Google Flights home page, each with a price history chart. A good habit is to keep tracking after you have booked. Most major US airlines no longer charge change fees on standard economy fares and above, so if the price drops you may be able to rebook and get the difference back as a travel credit. Basic economy fares usually don’t allow this.

Is the Google Flights price guarantee still offered?

Yes, but only on a limited scale. As of late 2026, Google’s terms say some flights carry a “Price guarantee” badge. If you buy one of these flights through Book on Google and the price of the same itinerary later drops, Google pays you the difference through Google Pay after you fly. The conditions are strict:

• You must be in the US, and the trip must be a one-way or round trip departing from the US. Multi-city trips don’t qualify.
• The fare must drop by at least $5. Each itinerary gets one payout, and total payouts are capped at $500 per calendar year.
• Any change or cancellation, by you or the airline, makes the booking ineligible.
• Google says it can change or end the programme at any time, so check the badge and the current terms before you count on it.

Most searches won’t show the badge at all, so don’t choose a flight just because it has one.

Using Google Flights to fly to a cruise

This is where the usual cheap-flight advice needs adjusting. Your ship won’t wait for a delayed plane. If you book your own flights rather than the cruise line’s air package, the cruise line has no duty to help you catch up with the ship. These habits help:

Fly in the day before

Search for a flight that lands the day before embarkation, and use the Price graph to compare that day with the day before it. A spare day costs a hotel night but protects a cruise worth thousands. For winter sailings from Northeast or Midwest cities, where snow delays are common, some cruisers allow two days. Our fly-cruise checks most people forget before they book cover the rest of the planning.

Use the Best tab, not the Cheapest

For the flight to the ship, use nonstop or protected single-ticket connections. A self-transfer itinerary from the Cheapest tab can save $40, but it is a bad trade if one late flight means missing the ship.

Search every airport that serves your port

Add all the realistic airports in one search, then add the transfer time and cost. Some ports are much further from the main airport than people expect. Our guide to cruise ports that are really far from the city explains why that matters.

Two patterns are worth knowing. For Port Canaveral, Orlando (MCO) usually has the most flights and the lowest fares, but Melbourne (MLB) can be closer and quieter. For Galveston, Hobby is closer and mostly served by Southwest, while Bush Intercontinental has far more airlines. Allow extra time for Houston traffic.

One-way and open-jaw tickets for repositioning cruises

Repositioning cruises (Fort Lauderdale to Barcelona, Seattle to Vancouver, or Miami to Southampton, for example) start and end in different places. In Google Flights, choose Multi-city and enter the outbound flight to the start port and the return from the end port. Then compare that price with two separate one-way tickets. On many transatlantic routes a multi-city booking with one airline or alliance is cheaper, and it keeps both flights in one booking. Domestic one-way fares in the US are often reasonable on their own. Use the Date grid on the return flight too, since you can usually choose to fly home on the day you disembark or a day later.

Watch the fare after you book the cruise

Set up price tracking as soon as your cruise is booked, even if the sailing is a year away. You will learn the normal fare for your route, which makes it easy to spot a genuinely good price. If you are still choosing a sailing, browse our cruise deals for 2027 and check flight prices for each option in Explore before you commit.

Book directly with the airline

When you select a flight, Google Flights shows a list of booking options: the airline itself and often several online travel agencies. Agencies are sometimes a few dollars cheaper, but booking direct usually makes changes, refunds and disruption handling simpler, because you deal with the airline instead of a middleman. This matters most on a trip to a cruise, where a schedule change needs fixing quickly. Choose an agency only when the saving is large enough to justify the extra hassle.

Once your flights are booked, our guide to CLEAR airport security explains whether it is worth paying to speed through the checkpoint.

If you still need to fly to your embarkation port, our guide to the best time to book flights for cheap tickets explains when fares are usually lowest and why flying in the day before is worth it.

One-way and multi-city searches are especially useful if you are planning a cruise that ends in a different country, and these repositioning cruise tips cover the flight logistics in more detail.

FAQs

How do I search Google Flights for flights to anywhere?

Leave the destination blank or open Explore. Google Flights shows a map of fares from your airport, which you can filter by travel dates, trip length and nonstop flights.

How do I set a flight tracker on Google Flights?

Sign in to your Google account, search your route and dates, and turn on the Track prices switch. You can track specific dates, a single flight or any dates. Alerts arrive by email.

Do all airlines show up on Google Flights?

No. Google Flights compares more than 300 airlines and travel agencies, but some carriers and some fares are missing. If a budget airline you know about doesn’t appear, check its own website too.

Can you book a flight directly on Google Flights?

Usually not. Google Flights sends you to the airline or a travel agency to complete the booking. The exception is Book on Google, which is offered on some fares and is required for the price guarantee.

Is the Google Flights Cheapest tab worth using?

It is worth checking, but read the details. Its lowest fares may use separate tickets or different airports. For anything with a fixed deadline, such as a cruise departure, the Best tab is usually the safer choice.
