The schedule for Wizzair's VNO-LTN, e.g. June 2012 for a Friday:
W6 8001: Dep VNO 6:10 - Arr LTN 7:00
W6 8002: Dep LTN 7:30 - Apr VNO 12:10
W6 8005: Dep VNO 18:10 - Arr LTN 19:00
W6 8006: Dep LTN 19:30 - Arr VNO 0:10
(W6 8005/6 is slightly later on Sun. No evening flight on Tue, Thu, Sat. Note they didn't have a Sat morning flight before).
Great for weekend trips ! And good news for the taxi drivers at VNO, who'll have bumper business around midnight.

BTW, please don't mix-up Lithuanians or Polish with Romanians. One could even consider Germans as 'Eastern Europeans' - many German immigrants in the UK are actually from the former GDR, so were probably born as Warsaw Pact members.
