This guide goes far beyond the basics. Here, you’ll learn exactly how Ryanair sets its prices, how to track fare drops, how to activate the right alerts, how to choose the perfect dates, how to search in the smartest way, and how to complete the purchase without paying unnecessary extras.

If your goal is to travel around Europe for the lowest possible cost, this article is your new roadmap.

1. Understanding How Ryanair’s Pricing Really Works

Before learning the step-by-step method, it’s important to understand the “logic” behind Ryanair’s low fares.

Ryanair operates with a dynamic pricing model, where ticket prices change constantly based on:

• Demand for that route
• How early or late you buy
• Competition with other airlines
• Flight load (how full or empty it is)
• Season, day of the week and holiday spikes
• Internal promotional campaigns

What does this mean for you?

It means that cheap seats always exist, but they are limited and move fast.
The key is knowing where to look, when to look, and how to spot a real deal — and that’s exactly what the next steps cover.

2. The Step-by-Step Method to Find Ryanair’s Lowest Prices

Below is the most effective system to consistently find the cheapest seats, based on thousands of user behaviors, search patterns, and pricing cycles.

Step 1 — Always Start With Flexible Search

If you begin your search with fixed dates and fixed airports, you will miss most promotions.

Instead, follow this structure:

1. Open Ryanair.com or the Ryanair app
2. Select “One-way” first (later you can build your return)
3. In the destination box, choose “Everywhere”
4. In the dates box, choose “Cheapest Month”

This is Ryanair’s most powerful feature.
It instantly shows:

• the lowest fares from your region
• for the entire month
• across dozens of destinations
• sorted by price

Most travelers choose a destination first and the date second.
To find cheap fares, you must reverse the logic: price first, destination later.

Step 2 — Search From Multiple Departure Airports

Ryanair prices can vary dramatically between airports only 1–2 hours apart.

For example:

• Flying from Milan instead of Bergamo
• Flying from Brussels Charleroi instead of Brussels Airport
• Flying from London Stansted instead of London Gatwick

Switching the departure airport can save you 60–80%.

Make a quick list of all airports within a reasonable distance for you and repeat the flexible search above.

Step 3 — Identify the Three Cheapest Weeks

Ryanair has clear “price valleys” during the year — weeks in which prices drop significantly.
These usually appear in:

• mid-January to mid-March
• mid-April to late-May
• late-September to early-December

By finding which weeks are cheapest for your departure airport, you maximize your chances of catching the famous €5.99 or €9.99 fares.

Step 4 — Activate Price Alerts (This Is Crucial)

Cheap fares on Ryanair often last less than 24 hours.

To never miss a drop, activate alerts on:

1. Ryanair App

• Save the route as “favourite”
• Enable push notifications
  The app often shows fares not displayed on the website.

2. Google Flights

• Enter route
• Activate “Track Prices”

Google Flights will email you every price change — extremely useful when fares decrease late at night or early morning.

3. Skyscanner Alerts

• Skyscanner finds fare anomalies
  Sometimes these appear earlier than on the Ryanair app.

Alerts are your safety net: they do the work while you sleep.

Step 5 — Understand Ryanair’s Daily Pricing Pattern

Ryanair adjusts many fares at night.
The cheapest prices tend to appear:

• between 22:00 and 09:00, especially
• Tuesdays, Wednesdays, and Thursdays

These are the days with the lowest flight demand, which is why the algorithm lowers prices to stimulate sales.

Step 6 — Use the “Fare Finder” Tool

Ryanair has an internal search engine that many people ignore: Fare Finder.

With it, you can:

• set a maximum budget
• see options across multiple countries
• filter by month or by region
• visualize unexpected promotions

It is the absolute best tool when you want to travel cheap but aren’t tied to a specific city.

Step 7 — Build Your Trip Seat by Seat

The cheapest fares usually appear one-way first.

To maximize savings:

1. Buy the outbound flight when it goes on sale
2. Wait for price drops
3. Buy the return flight later

Buying both legs at once often costs more because the system averages route prices.

Step 8 — Complete the Purchase Without Paying Extras

Ryanair’s low fares remain low only if you avoid unnecessary add-ons.

To keep your total at the promotional price:

• Travel with one small backpack
• Skip seat selection (Ryanair assigns one for free)
• Decline priority boarding unless absolutely necessary
• Skip travel insurance (you already have it through your credit card or external service)
• Review the “extras page” slowly — many travelers click through without noticing added fees

A flight advertised at €5.99 can quickly become €48 if you accept every optional service.
Only add what you truly need.

3. When Do Fares From €5.99 Actually Appear?

These ultra-cheap fares appear during Ryanair’s price cycles.
The strongest ones happen in:

1. Winter Bargains

Early January to early March — extremely low demand.

2. Spring Discounts

Second half of April through May — especially for mid-week flights.

3. Fall Promotions

Late September to early November — ideal period for cheap city breaks.

4. Flash Sales

Any time of the year, lasting from 4 to 12 hours.
These are announced through:

• app push notifications
• email newsletters
• Google Flights alerts

Flash sales tend to include a mix of:

• major cities
• secondary airports
• last-minute underbooked routes

Keep notifications ON and check twice a day.

4. Routes Most Frequently Included in Ryanair Promotions

While promotions vary, some destinations frequently appear with ultra-cheap fares because they have high volume and stable demand.

These include:

• Cities in Italy
• Cities in Spain
• Cities in Poland
• Cities in Portugal
• Cities in France
• Cities in Germany
• Cities in the UK
• Cities in Ireland
• Cities in Belgium

Secondary airports in these regions usually offer the lowest prices because they cost less for Ryanair to operate.

5. Advanced Tricks to Pay Even Less

1. Travel Mid-Week

The biggest price drops happen on Tuesdays, Wednesdays, and Thursdays.

2. Choose Early Morning or Late Night Flights

Low-demand times = lower ticket prices.

3. Avoid Peak Months

July and August are consistently the most expensive months.

4. Use Apps That Detect Mistake Fares

Useful apps include:

• Hopper
• Kayak Explore
• TravelDealz (Europe focused)

5. Don’t Search the Same Route Repeatedly

Airline systems sometimes interpret repeated searches as interest, causing prices to rise.

Use incognito mode or a different device.
