Great news for those who missed their aggressively chaperoned high-school trip: The time to book your long-deferred jaunt to Europe is right now, and you're heading out this winter. Roundtrip flights to London and Paris are going for as low as $300.
The best deal here is probably a January 25 flight from Los Angeles to London for $320 (or from San Francisco for $330 on January 13). Those of us who don't live on the West Coast will be happy to know, however, that there are roundtrip flights to Paris from Pittsburg and Boston for $300 in early December. Options from Chicago and Baltimore to Paris are a little pricier, but it'll still be under $400 in late January, which is reason enough to plan a trip.
