The best flight hacks for cheap flights are all about being flexible and doing a smart search. Try to be flexible with your travel dates and even your airport, because flying a day earlier or later, or from a nearby airport, can significantly reduce the price.

Use fare comparison tools like Google Flights, Skyscanner, KAYAK, or Momondo to see prices for an entire month and quickly spot the cheapest days to fly. Turn on price alerts for routes you care about so you get an email or app notification when the fare drops and can book fast before the deal disappears.

If you can, book most international trips 3–5 months in advance and avoid peak holidays and weekends, as those dates usually have the highest fares.

Google Flights is best for fast, flexible search, while Hopper is best for app-based predictions and push alerts.

Google Flights in simple terms
Google Flights lets you quickly compare flights from tons of airlines, dates, and even nearby airports in one place, making it great for research and planning. It shows helpful price trends and lets you turn on email price alerts, but you usually click out to the airline or a partner site to actually book the ticket.

Hopper in simple terms
Hopper is a mobile app that uses past price data and algorithms to predict whether prices are likely to go up or down and tells you whether to “buy now” or “wait.” It sends push notifications when it thinks prices are lowest and can offer extras like “price freeze” and credits if the price drops after you book through the app.

Mistake fares are airline price errors that make some tickets much cheaper than normal, sometimes by 50–90%.

What mistake fares are
A mistake fare (or error fare) occurs when an airline or online travel agency accidentally lists a ticket price that is far below the usual cost. These errors can be caused by typos, wrong currency conversions, missing taxes or fuel surcharges, or glitches in complex airline pricing systems. Airlines do not always have to honor these tickets, but many are still honored, especially if the airline does not catch the error quickly.

How to find mistake fares
Sign up for specialized deal alert services like Going, Dollar Flight Club, or Secret Flying, which scan thousands of routes and email or text you when they spot a possible mistake fare. Use tools like Google Flights and Skyscanner with price alerts turned on, and watch for prices that suddenly drop far below the normal range for that route.

Several flight deal alert apps are highly recommended because they watch prices for you and send deals straight to your inbox or phone. Going (formerly Scott’s Cheap Flights) and Airfarewatchdog are two of the most popular for serious savings on both normal and mistake fares.

Top recommended deal alert apps

• Going (Scott’s Cheap Flights): Sends handpicked deals and mistake fares from your chosen home airports, with a free plan plus paid tiers for more international and premium alerts.
• Airfarewatchdog: Tracks fares from your preferred airports and emails you when prices drop, or special promos appear, often including routes and airlines other apps miss.
• Skyscanner price alerts: Great if you are flexible, letting you track routes or even “Everywhere” searches and get notified when prices change.
• Google Flights alerts: Simple, free email alerts when a route you’re watching goes up or down, ideal as a baseline tool for almost every traveler.

Points and miles work best when used strategically, not randomly. The key is to earn them in the right places and redeem them for high-value trips, usually flights.

Smart ways to earn
Focus your everyday spending on cards that earn extra points in “bonus categories” like groceries, dining, travel, or online shopping, rather than using cash or a debit card. Aim to earn welcome bonuses (sign-up offers) by putting big planned expenses on a new card, but only if you can pay the balance off in full, so you are not paying interest.

Getting the most value
Learn your card’s transfer partners (airlines and hotels you can move points to), because moving points to a partner often gets you much better value than using them for gift cards or cash back. Before transferring, check that reward seats are available for the dates and routes you want, because transfers are usually non-refundable.

Saving money on family travel starts with flexibility and strategic planning. Travel during shoulder seasons (spring and fall) when prices are lower and crowds are smaller. Be flexible with your dates—even shifting your trip by a day or two can save hundreds.

Accommodation savings
Use accommodation alternatives like vacation rentals or hostels with private rooms, which often offer kitchen facilities to save on dining out. Look for destinations where your currency goes further.

Activities & extras
Consider free activities like beaches, hiking, and city walking tours. Sign up for airline and hotel loyalty programs to earn points on family trips, and use family discount passes for attractions and transportation.

The best booking sites for family flights combine comprehensive search options with family-friendly filters.

Google Flights is our top pick for its powerful search capabilities, calendar view, and family-specific filters like airline alliances and aircraft type.

Skyscanner excels at finding the cheapest options across budget airlines and traditional carriers. Momondo is great for uncovering deals other sites miss. For complex multi-city family trips, Kayak’s Explore feature helps you find affordable destinations.

Always compare prices on airline websites directly too—sometimes airlines offer family discounts or better seat selection that third-party sites don’t show.

Using travel credit cards effectively starts with choosing the right card for your spending habits.

Look for cards that earn bonus points in categories where you spend the most—groceries, dining, gas, or travel. Always pay your balance in full each month to avoid interest charges that negate your rewards.

Use your card for everyday purchases to accumulate points quickly, but never spend more just to earn points. Take advantage of sign-up bonuses by timing your card application before a large planned expense. Consider pooling family spending on one card to reach rewards faster.

Most importantly, understand your card’s redemption options—transferring points to airline or hotel partners often offers the best value, especially for international family trips.

Packing for family trips requires balancing essentials with entertainment and comfort.

Start with a family packing checklist organized by family member—clothing, toiletries, medications, and documents. Pack a carry-on bag with essentials: snacks, entertainment (tablets, books, coloring), change of clothes, and comfort items like blankets or stuffed animals.

Bring Ziploc bags for wet clothes, snacks, or toiletries. Don’t forget travel-sized first aid supplies, hand sanitizer, and wet wipes. For international trips, bring copies of passports and important documents. Consider packing cubes to stay organized, and leave some room in your luggage for souvenirs.

Travel insurance is worth considering for family trips, especially international travel or expensive vacations.

Good travel insurance can protect your investment if you need to cancel due to illness, injury, or other covered reasons. It typically covers trip cancellation, trip interruption, medical emergencies, lost luggage, and travel delays.

For families with children, medical coverage is particularly important since many regular health insurance plans don’t cover international medical expenses. Look for policies that cover pre-existing conditions and include cancel-for-any-work-reason (CFAR) coverage for maximum flexibility.

Rule of thumb: If you can’t afford to lose the money you’ve spent on the trip, travel insurance is worth the investment.
