A bunch of other blogs are writing this, but I wanted to pass along anyway because it’s a great deal a lot of people can use:
You can save 15% on any Delta or SkyTeam partner flight when you book before noon on September 24th on Alitalia‘s website and enter promo code WEEK15US after you select your flights.
That’s pretty much it – save 15% through end of schedule on all Delta flights. Nice.
