Paris at $507 RT

This is one of those deals that we can keep real simple...

It's a non-stop to Paris, with American, for about 500 bucks. Do you really need to hear more?

Dates might be limited to November, but that's hardly a downside — you'll be catching the last breath of autumn, the first winter holiday markets, and the drop in crowds that happens right before the surge. It's the sweet spot for anyone who wants to catch some "Christmas in Paris" scenery without "Christmas in Paris" problems. 

And hey, it's good enough for Lady Gaga :-)
