Traveling to Europe in the summer can burn a whole in your pocket; so why not head over there this winter.  Although not as good as some recent (and very brief) fares we've seen to Europe, United has dropped prices on certain routes for travel through April 12, 2011.  Travel to Europe Sunday through Thursday and return from Europe Monday through Thursday (to/from London is valid Mon-Wed only).  Other days of the week may be higher.  A Saturday night minimum stay is required as well as a maximum stay of 30 days.  Tickets require a 7-day advance purchase and must be booked by Jan. 10, 2011.

Sample fares include:

Chicago to Brussels $675 round trip non-stop tax included

Chicago to Munich $733 round trip non-stop tax included

Washington D.C. to Brussels $675 round trip non-stop tax included

Washington D.C. to Frankfurt $728 round trip non-stop tax included
