1) Quick setup: get clean results

• Open google.com/travel/flights. Sign in so you can save searches and receive alerts.
• Choose Round trip / One way / Multi‑city. Set cabin, travelers, and currency.
• Toggle One‑way for open‑jaw pricing tests (you’ll compare later).
• Start broad: use city codes with multiple airports, e.g., NYC, LON, TYO.

2) Use Date Grid to spot cheap combinations

After entering origin, destination, and a rough date, click Date grid. This matrix shows the cheapest outbound/inbound combinations over several weeks. Scan for green or low‑price cells and move your weekend by ±1–3 days. On many routes a Thursday–Monday beats Friday–Sunday by 10–30%.

• Micro‑flex: Shift departure by one day, return by one day. Recheck fees/times.
• Holiday windows: Search two weeks around the holiday to avoid peak spikes.
• Red‑eye leverage: Overnight returns often price lower and save a hotel night.

3) Read the Price Graph like a pro

Click Price graph to view fare trends over time. Use the slider to change trip length (e.g., 4–10 nights) and see cheaper periods. Spot falling trends and plan your purchase window. If a dip appears 3–6 weeks out, set an alert and wait for the drop to confirm.

Signal	What it usually means	Action
Steady upward slope	Inventory tightening	Buy soon or consider nearby dates/airports
Saw‑tooth pattern	Weekend surcharges	Shift to Tue–Thu or Sat–Tue
Sudden dip	Promo or competitive match	Book fast with free hold/cancellation

4) Turn on Price Alerts the right way

Toggle Track prices on your route or date range. You will receive email or app alerts when fares change. Create separate alerts for:

• A fixed date pair you actually want.
• A flexible date range for the month, so you don’t miss better windows.
• Alternative airports (e.g., SYD↔KIX and SYD↔ITM/KIX/UKB).

Tip: Keep alerts active after booking to claim a price drop via 24‑hour free cancel on OTAs or airlines that allow it.

5) Explore Map for flexible inspiration

Click Explore in the left menu. Set your departure city, choose “Any destination” or filter by continent, then set Duration and Interests (beaches, skiing, etc.). This is ideal when you only know your budget or trip length.

6) Routing tactics: nearby airports and open‑jaw

• Nearby airports: Add alternates like HND/NRT for Tokyo, KIX/ITM/UKB for Kansai, BKK/DMK for Bangkok. Re‑run the Date grid.
• Open‑jaw: Fly into one city and out of another (e.g., SYD→CTS, return HND→SYD). Often cheaper than back‑tracking and saves time.
• Self‑connect buffers: If mixing separate tickets, keep 4–6 hours between arrivals and departures, or overnight if visas allow.

7) Filters that matter in 2025

Stops & Duration

Use Stops and Times first. One‑stop with a decent layover often beats the cheapest two‑stop marathon.

Airlines & Alliances

Filter to preferred carriers or alliances for status/points. Consider basic economy restrictions before buying.

CO₂ filter

Google Flights marks lower‑emission options. Sometimes these are also newer aircraft with better comfort.

8) Multi‑city and long layovers

Select Multi‑city to build complex itineraries, such as Bangkok → Tokyo → Sapporo → Bangkok. Price each leg as one‑ways and as a multi‑city to see which is cheaper. Add a 20–24 hour stop for a “free” city tour without a separate ticket, subject to visa rules.

• Back‑to‑back test: If two one‑ways are cheaper, confirm baggage rules and change fees.
• Airport changes: Watch for inter‑airport transfers (e.g., NRT↔HND).

9) Where to book and how to stack savings

Google Flights usually redirects you to book with the airline or an OTA. For fewer headaches on schedule changes, booking direct with the airline is safer. To maximize savings:

• Price lock: If available, hold a fare for 24–72 hours while you confirm plans.
• Credit card perks: Use cards that add trip delay insurance, baggage insurance, or airline statement credits.
• Bundle hotels: After flights are locked, bundle hotels to chase package discounts.

FAQ

Is Google Flights the cheapest place to buy tickets?

It’s a powerful search tool. Final purchase happens with the airline or an OTA. Prices are usually the same, but promos can differ.

When is the best day to book?

No universal rule. Use Date grid and Price graph to find route‑specific dips, then set alerts.

Can I track prices for a whole month?

Yes. Track a flexible date range and fixed dates simultaneously for better coverage.

What about baggage fees?

Confirm baggage allowances on the booking page. Low‑cost carriers often exclude checked bags from headline prices.
