I received an email late last night regarding another sale that Delta is offering for flights within the Continental US. So long as you book economy tickets on Tuesday, Wednesday, or Saturday, you can get up to 30% off certain flights. The sale is limited to flights between September 28th and February 15th, and you have to book all flights by September 28th. Check the offer page for all the details!
While I was on the Delta deals website, I came across another deal – this between Anchorage or Fairbanks from many West Coast departure cities. This deal applies to both paid fares as well as award tickets.
