Back to the subject of airfares from UK to Ukraine.
I just got an excellent fare from Birmingham to Kiev of GBP191 incl. taxes on KLM for later this month, booked it via www.majortravel.co.uk .
First time I've used Major Travel but they came out significantly cheaper than the other travel sites that I normally frequent.
P.S. I went for KLM because they operate from Birmingham and it is only an hour away from me and a damn site easier to cope with than Heathrow. Also, airport parking, well just off the airport, at Birmingham is a mere GBP3.10 per day.
