I just received the regular Ryanair newsletter and, if you reserve before midnight on Monday 21st Feb, there are some bargains to be had.
Quite often the “sale” prices are not as attractive as they should be as you still need to add on fees & taxes, which can sometimes more than double the original price. But the current sale includes flights with NO fees or taxes.

For example, you could pick up a return flight from Nantes to East Midlands in March for just €22. There are no other fees or taxes to pay, other than the credit/debit card handling charge. (We are waiting to get hold of one of the pre-paid Mastercards, which will save us having to pay the card charges too. We’ll write up our experiences with that when we’ve tried it out.)
So, if you’re looking to get to France for next to nothing (come to visit us!), or head back to the UK for a quick visit, you’d better get booked quickly as these mega-cheap flights tend to sell out very quickly!
