I just came across this offer while going through my wife’s American Express offers. She seems to get the better ones that I don’t get on either my EveryDay Preferred or Starwood Preferred Guest Business card.
Get a one-time $50 statement credit by using your enrolled Card to spend a total of $300 or more on purchases made directly with any airline by 9/15/15. See terms and conditions for details and exclusions.
I think this is an easy & self-explanatory one that any readers of this blog can take advantage of. Just make sure the purchase is directly with the airline and not through a third party like Orbitz, Priceline, etc.
I’ve read that there is a better version of this offer (spend $300, get $75 back) and that it’s highly targeted. Hopefully, you find this offer in your American Express accounts. Any discount on airfare is a welcome one!
