Ryanair’s latest flash sale takes £20 off return flights booked by 23 September, for travel between 23 September and 31 December. It is a straightforward saving for anyone with an autumn trip in mind.
The sale page currently lists London Stansted to Milan Bergamo from £12.99, Szczecin from £14.07 and Poznan from £14.28. Taking £20 off a return makes those short-break fares much more tempting.
The offer is subject to availability, so use the sale page to price both directions together before you pay. It is for return flights, not a standalone one-way fare.
