The only place you're going to find the actual sale routes is in the terms and conditions.
Ryanair is known for their budget-friendly fairs, but a recently announced winter sale takes this to a new level. The airline is offering 50,000 €9.99 airplane tickets—that's $11—through Monday. The only catch: You're going to have to do a bit of legwork to find them as they're not directly broadcasted on the main page. According to the terms and conditions, the offer is only available for select routes (read on for those) between two time periods: October 30th, 2015 through November 2nd, 2015 and November 1st, 2015 through February 29, 2016. Tickets must be purchased 14 days in advance, taking those last-minute flights out of the offer. Also, Business Class is not available when using this deal.
For a full list of included routes, head on over to the Ryanair website. Happy searching!
