Delta has dropped prices (again!) on several of its nonstop flights to Europe. It's rare to see these prices in the $400s roundtrip from hub cities like Atlanta (ATL), Detroit (DTW), Minneapolis (MSP), and Salt Lake City (SLC). And we're also seeing some unusually low fares on nonstop flights from Boston (BOS) for under $300 roundtrip. Cheap nonstop fares to Europe are available from many cities, including Los Angeles (LAX), New York (JFK), and more, with fares as low as $225 roundtrip.
Some of these nonstop flights may be operated by partner airlines Air France, Alitalia, KLM, or Virgin Atlantic. American Airlines, British Airways, and other carriers may be matching prices along some routes and lower fares may be available with a connection.
Travel dates vary depending on the route. Most are available for travel between late October and early April. Cheap flights to London are available from September through mid-June, and other routes may only be available in limited months.
Peak holiday travel times in late December and early January are blacked out, though you may find availability over New Year's if you stay through the first week of January.
The minimum stay required to get these prices varies by route. Most require a Saturday night or a 7-night minimum stay. A few only require a 2-night minimum stay, which is extremely rare for cheap flights on legacy carriers to Europe. Click on the fare details for more info.
This sale is unadvertised and fares may jump at any moment. Try many different sites if you are finding prices jumping as inventory can go quickly and may still be available on another booking engine.

Basic Economy fares only include a carry-on bag plus one personal item. The first checked piece of luggage will cost $60 each-way. On some routes, it may be the same price (or cheaper) to upgrade to a Main Cabin Economy fare. Main Cabin Economy fares include one free checked bag.
Seats will be assigned at random upon check-in for Basic Economy. You may be able to pay a fee to choose a specific seat. Main Cabin Economy fares include advanced seat assignments.

Upgrading to Main Cabin Economy will cost an additional $90-$140 roundtrip on most routes. Certain travel dates and/or routes may be much more to upgrade. This type of fare will include one free checked bag, seat selection, and is eligible for ticket changes (fee applies)/upgrades.
Some routes will have lower fares for connecting flights on other carriers. Make sure to compare the savings with the total travel time to decide if it's a better deal for you.
As an example, I found a flight departing Boston BOS on Wednesday, November 13, with a return flight from Paris CDG on Wednesday, November 20, for $280 roundtrip.
