This sale is epic! Delta has put its entire network from the US to Europe on sale for travel this fall, winter, and early spring. Some flights are operated by SkyTeam partner airlines Air France, Alitalia, KLM, or Virgin Atlantic. Other airlines have matched prices in a few markets. Nonstop flights are as low as $319 roundtrip.

Although we've seen our fair share of flash sales to Europe lately, this one is the most widespread sale we've seen in a long time. It is extremely rare for Delta to price its nonstop flights to Europe this low on many of these routes, so if you prefer to fly nonstop on a legacy carrier, don't pass up this opportunity for a cheap flight to Europe.

Travel on most routes is valid from October 28, 2018, through March 31, 2019. Travel over Thanksgiving week is mostly available, but prices will be higher for peak Christmas or New Year's travel. If you're able to take an extended trip, you may be able to book a trip over these holidays. UK routes have availability for travel through mid-May or mid-June, with a 28-day advanced purchase required. All fares require a minimum stay of 7 nights.

Most of these nonstop fares are Basic Economy, which only includes a carry-on bag plus one personal item and doesn't allow advanced seat selection or ticket changes. Checked bag fees start at $60 each way for Basic Economy fares, so if you would need to check a bag, opt to pay for the standard Main Cabin Economy fare.

The upgrade to Main Cabin Economy varies between $70-$130 for most of these routes. A few routes are only slightly higher to upgrade and if it was $25 or less to upgrade to Main Cabin Economy, I just listed the Main Cabin price, which includes one free checked bag, advanced seat selection, and the ability to make ticket changes for a fee. Meals are included regardless of the fare you purchase.

This sale is unadvertised and prices may jump at any time. Book quickly! These fares may not last too long. You'll have 24 hours to cancel for free if your plans change.
