Fly high-class for low quid. Soar to Europe’s top cities this fall and winter on British Airways. There’s a stopover in their hub city of London, but this is a great chance for budget conscious flyers to afford them. I put them in the class of Singapore Airline and Virgin Atlantic in terms of passenger comfort and service.

The destination cities on sale are Amsterdam, Athens, Frankfurt, London, Madrid, Paris, Prague, Rome and Vienna.

Sale fares good for travel from October 22, 2009 through March 28, 2010 (December 21-23, 2009 excluded). Sale ends on September 24, 2009. Read more.
