Ryanair has a flash sale running with fares from £14.99 one way, bookable until 11 September 2026. That headline fare is genuinely low even by Ryanair standards: Liverpool to Madrid or Rome Ciampino from £14.99 one way, and Barcelona from £15.99, prices you’d typically pay two or three times more for at this notice.
This is one of Ryanair’s regular flash sales rather than a single-route promotion, covering dozens of European destinations at once. Travel must start between 11 September and 31 October 2026. We checked availability from Liverpool; Ryanair’s flash sales typically run from multiple UK bases simultaneously, so it’s worth checking your own nearest airport on ryanair.com.
What’s on offer
We checked Liverpool John Lennon departures on 8 September 2026. Here’s what the Ryanair flash sale looks like on the ground:
| ROUTE | FROM | TRAVEL WINDOW |
|---|---|---|
| Madrid | £14.99 | 11 Sep–31 Oct 2026 |
| Barcelona | £15.99 | 11 Sep–31 Oct 2026 |
| Rome Ciampino | £14.99 | 11 Sep–31 Oct 2026 |
| Dublin | £14.99 | 11 Sep–31 Oct 2026 |
| Porto | £16.99 | 11 Sep–31 Oct 2026 |
| Warsaw Modlin | £16.99 | 11 Sep–31 Oct 2026 |
Prices were live on 8 September 2026. They vary by travel date, departure airport, and how many seats remain. Ryanair’s flash sales typically run from multiple UK bases at once, so it’s worth checking your own nearest airport on ryanair.com.
| SALE DETAIL | INFO |
|---|---|
| Fares from | £14.99 one way |
| Book by | 11 September 2026 |
| Travel window | 11 Sep–31 Oct 2026 |
| Bags included | Personal bag only (40×30×20cm) |
| Cabin bag fee | ~£6–£10 each way |
Is this genuinely good value?
Yes, for flexible travellers going light. Fares under £20 one way to Spain or Italy are hard to find outside of a flash sale; comparable non-sale fares on these routes typically run £50–£90 or more each way. A return to Barcelona or Madrid at these prices, even with a cabin bag added both ways, still comes in well under what you’d normally pay.
The main caveat is what the base fare actually includes. Ryanair’s cheapest ticket covers only a small personal bag that fits under the seat (40×30×20cm). A cabin bag for the overhead locker costs extra, typically £6–£10 each way when booked in advance, more if you add it at the airport. If you’re travelling as a family or need hold luggage, your total will climb well above the headline fare.
Seat selection is also paid. Free seats are available at the back of the plane, or you can pay from a few pounds to choose your spot. For a short city break where you’re packing light, none of this changes the fundamental value: these are genuinely cheap fares for the time of year.
The verdict
If you’ve been weighing up a short autumn break to Spain, Italy, or further afield in Europe, this is the kind of sale that makes the decision easier. The fares are real, the routes are popular, and the prices significantly undercut what you’d pay booking outside of a promotion. The travel window runs to 31 October, so there’s enough flexibility to plan properly.
It won’t work for everyone. If you need a specific airport or date that isn’t discounted, the sale won’t help you. And if you’re travelling as a group with luggage, factor in the extras before assuming the headline price applies. But for a solo traveller or couple who can pack into a personal bag, this is worth acting on soon. The booking deadline is 11 September 2026.

A few tips before you search. Tap Book Now to go straight there.
- Search directly on Ryanair.com, as sale fares don’t always appear on comparison sites.
- Be flexible with your dates: prices vary day by day, so shifting by even a day or two can make a difference.
- Add any cabin bag or hold luggage at the same time you book the flight, as it’s always cheaper then than at the airport.
- Check multiple UK airports, not just your nearest. A short drive could save you a meaningful amount on the base fare.
About Ryanair
Ryanair is Europe’s largest airline by passenger numbers, operating over 230 destinations across Europe and North Africa from 90+ airports. Its model is low base fares with paid extras: luggage, seat selection, and priority boarding are all charged separately, which is how the airline keeps the base fare low.
On punctuality, Ryanair typically sits in the middle of the pack among European low-cost carriers. If you want to time future bookings around sales, see our guide on when Ryanair has sales. For short trips where you’re packing light, it’s often the cheapest fare on a route. For bag guidance, see our best carry-on bags for Ryanair guide.
If you’re planning a trip and want to know the current Ryanair hand luggage size rules before you pack, they’re stricter than most airlines. The personal bag limit is 40×30×20cm for the under-seat locker. Worth double-checking before you get to the gate, as Ryanair enforces its size guidelines consistently. See our guide to Ryanair hand luggage size in 2026 for the full picture on what’s allowed.
Frequently asked questions
When does the Ryanair flash sale end?
The sale runs until 11 September 2026. Book before then to access the discounted fares, though Ryanair often follows one flash sale with another, so check ryanair.com if you miss this window.
What dates can I travel on the Ryanair flash sale?
Travel must start between 11 September and 31 October 2026. Outbound flights must depart within this window to qualify for the sale pricing.
Which UK airports are included in the Ryanair flash sale?
Liverpool is confirmed in this sale, with fares to destinations including Madrid, Rome Ciampino, Dublin and Barcelona. Ryanair’s flash sales typically run from multiple UK bases at once, so check Ryanair.com for your nearest airport.
Is luggage included in Ryanair flash sale fares?
No, only a small personal bag (40×30×20cm) that fits under the seat in front is included free. A cabin bag for the overhead locker costs extra and must be booked in advance for the best price.
How much does a Ryanair cabin bag cost?
When booked at the same time as the flight, a cabin bag typically costs £6–£10 each way. Adding it later, especially at the airport, costs considerably more.
Is the Ryanair flash sale worth booking?
Yes, for travellers who can pack into a personal bag or are happy to pay the cabin bag fee. Fares from £14.99 to Madrid or Rome Ciampino, and £15.99 to Barcelona, are well below typical prices on these routes, and the value holds with a cabin bag added.
Can I change my booking after buying a Ryanair flash sale fare?
Yes. Ryanair allows flight changes, but a change fee applies and the fare difference is charged if the new flight is more expensive. Changes are easier and cheaper if made well in advance rather than close to departure.
