If you're looking for a cheap vacation, you’ll want to know the best travel websites to use. And if you’re tired of wondering which sites are best for each part of your trip planning, we’ve got you covered.
Here are some of the best travel sites we’ve found to help you bag bargains on airfare, lodging, car rentals and all your other travel needs. Get a good deal on travel insurance, score discounts on international train tickets or rent a car on the cheap — whatever you need, there's likely a deal or discount for it. Plus, check out the best fall travel deals for even more ways to save.
Best of all, almost all of the travel websites are free to use. Bon voyage!

Best websites and apps to save on airfare
Keeping up with airfare prices has gotten easier thanks to sites like Google Flights and Kayak. To use them, just type in your home and destination airport, pick the flights that work best for you and then set an alert to track the price. After that, you'll receive emails showing if your tracked flight went up or down in price. Both sites also let you see which days are cheaper to fly in that month.
Airfarewatchdog is another site that lets you search flight deals, so take a look and compare your options between sites to find the best price available.
If you haven’t decided on where exactly you want to go, sign up for Going (formerly known as Scott’s Cheap Flights.) Going's newsletter comes straight to your inbox with deals on domestic and international locations. However, to access all domestic and international economy deals with the site, you'll need to pay for a membership, which costs $49 annually.

Best websites and apps for flight information
Once your flight is booked, you’ll want to keep tabs on gate changes, layover information and more to ensure your travel goes as smoothly as possible. Flight delays and cancellations can really put a wrench in your plans, but staying up to date on current flight and airport information can make managing these situations easier.
FlightStats.com can help you plan a smooth trip by advising you on the best time of day to fly from a specific airport and which terminals to avoid when connecting flights. You can also view live updates of flight delays and sign up for free e-mail and phone alerts. For $2.99 per month, a premium membership provides flight alerts and access to historical flight data. Flightaware.com also tracks and predicts flight delays.
If you’re delayed by weather or some unforeseen event, it pays to act quickly. The TripIt Pro smartphone app ($49/year) will send you alerts about cancellations, delays or gate changes, sometimes even ahead of an airline announcement. Use it to locate alternate flights, find out when better seats are available, get fare refund notifications, track your rewards program points and more.

Best websites and apps to save on hotels
Hotels.com lets you search just one site for accommodations at hundreds of thousands of properties. Plus, its rewards program is simple: earn OneKeyCash for every dollar spent on eligible hotels, vacation rentals, flights, car rentals and more when you book on Hotels.com (or partner brands).
Similarly, HotelTonight is an app that lets users book hotels at low last-minute rates. Priceline Express Deals helps you find the best bargains, but there’s a catch. Priceline doesn’t tell you which hotel you’re booking until after you pay.
And try TripAdvisor.com for a detailed list of rated hotels (and excursions) that are close to your destination. The site links you to partner sites, such as Expedia and Travelocity for fulfillment. Click on the "check rates" button and select the site or sites you’d like to try — a new window with results will open for each partner.
And to save even more, make sure you avoid annoying hotel fees. Also, check your credit card rewards. Some of the best travel credit cards offer deals and discounts on hotel stays. For example, the Citi Strata Premier card offers a $100 annual hotel and earns 10x points booked on hotels through the card's travel portal.

Best websites and apps to save on vacation rentals
Vacation rentals are an especially good value for groups because they generally offer more space and amenities for prices similar to or less than hotel rates, particularly if you look at it on a per-bed basis. Check out VRBO and Airbnb to find the perfect experience. If you've never stayed at a short-term rental check out our list of things you should know before you book your stay.

For Marriott loyalists, Marriott Bonvoy lets you browse its 30-brand portfolio — which includes more than 2,000 private homes.
At the other end of the scale, if you don’t mind college-dorm-level amenities, check out Hostelworld.com as a way to save. The site lists more than 17,000 hostels in over 180 countries around the globe and includes reviews.

Best websites and apps for cruises and vacation packages
At CruiseCompete.com, more than 500 travel agencies vie to give you the lowest prices for dates, ports and ships you specify, whether you’re booking a cruise well in advance or at the eleventh hour. You set up a CruiseCompete account, and they send you their best offers without ever seeing your personal information.
Kayak.com and Tripadvisor.com will also knit together vacation packages for you. Just type in your destination and travel dates to get the best prices.

Best websites and apps to save on rental cars
Hotwire often offers the best-published deals on cars by collecting rates from its eight rental car company partners, including Alamo, Enterprise and Hertz. The site also offers "hot rates" from rental companies that aren't identified until after you’ve paid.
And while Hotwire does offer some good prepaid rental car deals, in certain international cities for the best overseas auto deals you should check out AutoEurope. It offers rentals at more than 20,000 locations worldwide, and customer service is available 24/7.
AutoSlash is also a good site to find rental deals, as it will apply the best coupons and discount codes to your rental and re-book your reservation if the system finds a better deal.
If you rent a car on your next vacation, consider booking it with a credit card that covers rental car insurance.

Best websites and apps to save on international train tickets
Trains are often the fastest and cheapest way to travel within and between European countries. Our favorite for checking timetables and booking tickets on European train lines is RailEurope. But you might be able to catch better deals directly from European railways’ sites if you don’t get lost in translation — and make sure you have what you need to travel to Europe as an American!

Best websites and apps for travel insurance
You never know when an emergency will spoil your travel plans. That's what travel insurance is for. But don't just go for the default options from travel agencies and travel providers. At Squaremouth, you can compare plans and prices from multiple insurance providers with just one search and narrow your search results by specifying the kind of coverage you need. Another option is InsureMyTrip.com.
