Heading back to school (or even just seeing the end of summer) can be tough.

In fact, we'll readily admit it: we're already dreaming of our next holiday. Especially since the temperatures are set to drop very soon. Thankfully, Ryanair have found the perfect cure to banish the end-of-summer Blues and have launched a huge sale - with prices as low as €9.99 for one way. From Dublin, you can get to Bournemouth or London for under €10 each way; or you can head to Glasgow, Newcastle, Manchester or Luxembourg for under €15 each way. There are also flights to Cologne, Frankfurt, Sofia, Split, Pisa, Milan and Madrid (among many, many others)  available for €20 each way. If you're planning on flying from Shannon, you can get to Bristol, Manchester, Malaga, Wroclaw, Krakow and Alicante for under €25 each way. And there are flights to Barcelona, Faro, London, Liverpool and Bristol available from Knock for under €25 each way. Finally, from Kerry, you will be able to fly to London, Frankfurt and Alicante from under €23 each way. The deal is valid for flights traveling in November - so it is perfect whether you're looking to book a pre-Christmas break; are planning to go see some of this year's stunning markets; or if you're simply planning a mini-break. You better be quick, though. With deals like this, we imagine these seats won't be sticking around for too long. You can check availability - and the full list of routes on offer - here.
