American Express has a great new Amex Offer for 20,000 Membership Rewards points on a cumulative $1,000 in spending with Air France by April 14th, 2017. This offer may be targeted, but it appears on all of the MR-earning cards in my household.
The terms clearly state that is is valid for one or more transactions, meaning that you do not need to spend the full $1,000 in one charge. The terms also state that the charge must be made on airfrance.us online or via the Air France mobile app.
This is a terrific offer as it amounts to 21x-25x depending on which Amex card you use to pay for your ticket. The ideal scenario would be to make a $1,000 purchase on an American Express Platinum card (personal version) for 5x airline spend plus the 20k bonus for 25k Membership Rewards points.
With already decreasing airfares in both economy and business class cabins, this offer could be quite valuable. A quick search yielded results of $399 for round trip economy class from Boston to Copenhagen on Air France in September:
If adding extra checked bags or upgraded seat selection, you could get to the $1,000 spend and earn a nice rebate in the form of Membership Rewards on top of the miles you will earn from the flight. You may even find tickets priced a bit lower and squeeze in three tickets for around $1,000.
This offer expires April 14th, but it may disappear at any time, so I suggest adding it to your eligible cards as soon as possible. See our Complete Guide to Amex Offers to review ways of adding the offer to multiple cards.
