When airlines fight, we win—and today we're winning big: Passengers in New York, San Francisco, and Los Angeles can find flights to Hong Kong for as low as $348 round-trip thanks to what looks like a fare war between Delta and United. These fares are practically unheard of for a route that usually costs at least $1,000 round-trip. The deal has been available on and off for the last 24 hours as the airlines continue to lower their prices (it originally cost around $450). If you're interested in this deal, book now, because there's no telling how long these fares will remain. Added bonus? Some of the United flights are on ANA, one of our reader's favorite international airlines.

The fares are available for a variety of dates from September through December (excluding Christmas). To book, head to Google Flights and use the date box to check the calendar for the cheapest dates. If you take those dates to Priceline, which has a 24 -hour cancellation policy, you might be able to get an additional $10 to $20 dollars off on select dates. Ready, set, book!
