Update: Some offers mentioned below are no longer available. View the current offers here.Delta’s decision to use variable pricing in place of a fixed award chart means that it’s often hard to redeem SkyMiles at a (consistently) good value. The saving grace is Delta’s frequent flash award sales, which let you book awards to select destinations at very low prices.We’ve seen sales recently to every corner of the world, including Asia, Australia and Africa. Doctor of Credit is reporting that Delta has extended its flash sale awards from earlier this week (we’ve updated this post with new examples and dates), and buckle up because it’s a long list. You can see the full set of offers here, though I’ll break them down by region to make it a bit easier to follow. Also pay close attention as each region has different eligible travel dates, though all purchases must be made by April 10th. Also note that Delta is offering slightly different sale prices depending on your departure city, more so than with previous flash sales.If you’re in need of SkyMiles, remember that you can instantly transfer American Express Membership Rewards points to Delta at a 1:1 ratio.AsiaRoutes: Flights from Boston, Los Angeles, Seattle and New York JFK to Shanghai or BeijingCost: 200,000+ SkyMiles and ~$35 round-trip in Delta OnePurchase By: April 10Dates: June 23 to August 31EuropeRoutes: Flights from New York JFK to London or Zurich / Indianapolis to Paris / Portland and Salt Lake City to London / Atlanta to Brussels / Orlando to Amsterdam / Detroit to London and MunichCost: 32,000+ SkyMiles and ~$60 round-trip in economy (taxes and exact award costs vary by route)Purchase By: April 10Dates: April 25 to May 31Latin America & CaribbeanRoutes: Flights from Atlanta to Nassau, Bermuda and Grand Cayman / New York JFK to Aruba, Nassau and St MaartenCost: 18,000+ SkyMiles and ~$80 round-trip in economyPurchase By: April 10Dates: June 1 to June 30Domestic USRoutes: Flights from Los Angeles to Las Vegas and Phoenix / Minneapolis to Denver and San Francisco / Raleigh Durham to Tampa / Salt Lake City to San Francisco / Seattle to Los AngelesCost: 11,000+ SkyMiles and $11 round-trip in economyPurchase By: April 10Dates: May 1 to June 27Here are a few examples of what you can book:Sign up for our daily newsletterEmail addressSign upI would like to subscribe to The Points Guy newsletters and special email promotions.
