United & Lufthansa are offering a joint fare sale to Europe for departure dates this fall/winter. You can get to popular travel cities like London, Paris, Amsterdam, Vienna, Madrid, Athens, Rome, and Munich, and by traveling in the off-season you can save big on airfare.

Some of the sample fares are below (each one is listed one-way, so don’t drool too much until you double it for round-trip prices):

• New York-Munich – $211
• Philadelphia-Dublin – $219
• Washington-Frankfurt – $221
• Chicago-Vienna – $246
• Boston-Frankfurt – $257
• Houston-Barcelona – $352
• Denver-Rome – $395

Fares quoted don’t include some fees and taxes. You’ve got to buy your tickets by July 8, 2008, and travel must commence between October 27-December 11, 2008 or December 25, 2008-March 25, 2009 for the best prices. If you’d like to travel between September 1-October 26, 2008, there are still sale fares, but they’ll be a bit higher. Travel must occur Monday-Thursday, the trip must include a Saturday-night stay, and you can’t stay longer than 30 days. As always, read all the details before you book.
