Wizz Air are now flying to Lviv and Kiev in the Ukraine. Outbound flights to Kiev are are all £67.99 from Luton airport.....but on the way back they are approximately 48 UAH, which I calculate to be about £4!!, so about £70 return inc taxes(I think).
This must be due to the economic problems in the Ukraine right now. There are also internal flights to Lviv, and Smiferopol which is the Ukrainien seaside for the same price!. There are also flight to Germany and Norway from Kiev and Lviv for the same kind of price.
So you have a return flgiht from the UK for about £70, or of course you can visit a nearby country and fly back from Kiev or Lviv for peanuts,
I'm presuming due to the favourable exchange rate, other things in the Ukraine will be cheap also.
So forget Paris this spring time, have a bargain break in Kiev I say :)
