We don’t normally bother with this sort of thing, but the TravelZoo newsletter recently sent out a bunch of awesomely cheap flights from D.C.. New York, Boston, Shanghai and more are all within your reach for really, really low prices on United. You have to book your flight by this Friday (8/8) to get the discounted fares, but you can travel through November. Since getting to the grocery store costs about $48 dollars these days, a $64 flight to Boston seems pretty notable. That’s a whole lot cheaper than Amtrak, too.
