Heads up, budget travelers! Check your Amex Offers because you might have a deal to save $40 on Frontier Airlines flights when you spend $200 or more. This offer is valid through December 31, 2023, so there's still time to snag it! Just make sure you book directly with Frontier via their US website or mobile app and that your flight originates in the US. This is important because even small savings can make a big difference when you're flying on a budget airline. The offer includes things like baggage fees (sadly) and even allows for multiple transactions to reach the $200 threshold. However, it excludes travel insurance, car rentals, hotels, and gift vouchers. To see if you have the offer, log into your Amex account and scroll through your available offers. If you see it, be sure to add it to your card before making your purchase! It's free money (well, $40 back!), so don't leave it on the table.
