1. Dollar Flight Club
Started by Jesse Neugarten, Dollar Flight Club is all about making travel affordable by alerting users to flight deals that can be as much as 90% off. The platform keeps a constant eye on flight prices and sends members curated deals, helping them snag incredible savings.
Alert Types
Members receive flight deal alerts via email in a newsletter format, featuring handpicked discounts. If you’re looking for faster notifications, SMS alerts are available – but only if you’re subscribed to the Premium+ plan.
Membership Options and Pricing
Dollar Flight Club offers three membership plans, catering to different budgets and travel preferences:
Plan | Price | Deals/Week | Airports | Dream Destinations | Flight Types | SMS Alerts |
---|---|---|---|---|---|---|
Basic | Free | 1–3 | 1 | Limited | Economy, Domestic | No |
Premium | $69/year | Daily | 4 | 10 | Economy, Domestic & Intl. | No |
Premium+ | $99/year | Daily | 4 | 10 | Economy & Business, Intl. | Yes |
The Basic plan is free and gives access to 1–3 domestic flight deals per week from a single airport. For $69 a year, the Premium plan unlocks daily alerts, including mistake fares, and expands coverage to four airports and 10 dream destinations. The Premium+ plan, priced at $99 annually, takes it a step further by including premium cabin alerts (like business and first-class) and SMS notifications, along with priority customer support.
While Dollar Flight Club used to offer lifetime memberships, this option is no longer available. However, new Premium subscribers can test the service with a two-week trial for just $1. If you’re interested in Premium+, you’ll first need to sign up for the Premium plan.
Key Features
Dollar Flight Club specializes in finding mistake fares and secret deals, helping members save big on both domestic and international flights. Premium and Premium+ members can track up to four departure airports and set up to 10 dream destinations for personalized deal alerts. While Basic and Premium plans focus on economy flights, Premium+ members get access to premium economy, business, and first-class flight deals. Additionally, Premium+ subscribers enjoy extra perks from partner companies and faster customer support.
Pros and Cons
What’s great: Dollar Flight Club covers both domestic and international routes, with Premium and Premium+ members receiving daily alerts that often include mistake fares. The ability to set dream destinations makes the service more personalized, and the Basic plan lets new users try it out without spending a dime.
What’s not so great: The Basic plan is limited to a single airport and only 1–3 deals per week. Premium members miss out on business class alerts, which are exclusive to Premium+. Also, the best deals may not always match your ideal travel dates or destinations, so some flexibility is necessary to take full advantage of the service.

2. Skyscanner
Skyscanner is a flight search engine that compares prices across airlines and travel agencies, making it a go-to tool for finding affordable tickets, especially when booking in advance.
Alert Types
Skyscanner lets you set up email price alerts to track fare changes for your chosen routes. Once you create an account, simply click on “Get Price Alerts” to activate notifications. You can manage these alerts directly through your account settings.
Key Features
One standout feature is its multi-airport support. When setting up alerts, you can include nearby airports for both departure and arrival. This broadens your options, increasing the likelihood of snagging a better deal and adding flexibility to your travel plans.
Another handy tool is the “Anywhere” search, which helps you find the cheapest available flights to destinations worldwide. Skyscanner also factors in baggage fees, giving you a more accurate picture of the total cost. The fare calendar and price trend tools visually display pricing patterns, making it easier to spot the best days for travel.
These tools make Skyscanner an adaptable choice for travelers looking to save money while planning their trips.
Pros and Cons
What works well: Skyscanner is consistently praised for its ability to find low fares, especially for advance bookings. Its user-friendly design makes setting up and managing alerts straightforward. The multi-airport search and flexible date options enhance your chances of saving money. Best of all, the service is completely free – no membership fees required.
What could be better: Skyscanner isn’t as strong when it comes to last-minute bookings, and its response times can sometimes feel sluggish. The filtering options are somewhat limited, and some of the travel agencies listed may not be familiar. It’s a good idea to do a bit of research before finalizing your booking.

3. Kayak
Kayak is a flight search engine that scans hundreds of websites to find competitive airfare deals. It also offers a robust price alert system that keeps you updated via email, mobile push notifications, or text messages. To access these features, you’ll need to set up a free account.
In addition to price alerts, Kayak helps with travel planning by providing detailed flight management updates. These include check-in reminders, departure alerts, delay notifications, and gate change updates, ensuring you’re always informed about your journey.
Key Features
Kayak’s price prediction tool analyzes millions of fares daily and forecasts trends with an accuracy rate of about 85%. It allows you to monitor fares for specific travel dates or broader date ranges. Whether you’re tracking a general route or have fixed travel dates, the system adapts to your needs.
Even after booking, you can set alerts to monitor prices and rebook if a significantly better deal emerges. Kayak also scans prices from both airlines and online travel agencies, giving you a comprehensive view of available options. Additional tools like the Best Time to Travel feature and price forecasts help you identify seasonal trends and ideal booking windows.
These tools make fare tracking seamless and efficient.
Pros and Cons
Pros: Kayak provides extensive fare coverage and boasts a price prediction accuracy of about 85%, which can help travelers time their bookings confidently. Fare alerts alone can save users an average of 5–10% on airfare. Plus, the option to receive post-booking alerts ensures you won’t miss out on better deals after you’ve already made a reservation.
Cons: The variety of alert options can feel overwhelming, and acting quickly is often necessary to snag the best deals. For short-term predictions (within three weeks), accuracy is around 80%, but it decreases for longer-term forecasts. Additionally, some deals are fleeting, so delays in responding to alerts could mean missing out.

4. Skiplagged
Skiplagged keeps you in the loop with flight price alerts through email and push notifications on its mobile app. This two-pronged approach ensures you never miss a deal, delivering updates straight to your inbox or phone.
Alert Types
To get email alerts, log into the Skiplagged website and activate the “Create a Price Alert” option. Once set, the platform monitors your chosen flights and notifies you whenever prices drop.
If you prefer mobile updates, download the Skiplagged app for iOS or Android. Simply tap the heart icon while searching for flights to track them, and the app will send you push notifications about any price changes.
