How to book Flying Blue Promo Rewards flights
Book Promo Rewards tickets on the Air France or KLM website. Log in to your account, then click the "Book with Miles" tab on the home screen. After, enter your desired itinerary before clicking "Search flights."
If you don't see a Promo Rewards option on your desired travel date, look at surrounding dates for a price that matches the Promo Rewards rate.
Once you find a flight you'd like to book, select it and follow the on-screen prompts to complete your reservation. If you plan to transfer credit card rewards to book this, make sure you find award space first; then, place your ticket on hold and transfer your points or miles.
Also, be sure to check your transferable reward accounts to see if there are any available transfer bonuses.

How to earn Flying Blue miles
Boosting your Flying Blue balance is easy because the program partners with major programs that have transferable points and miles.
You can transfer rewards at a 1:1 ratio from American Express Membership Rewards points, Bilt Rewards Points, Capital One miles, Chase Ultimate Rewards points, Wells Fargo Rewards points and Citi ThankYou Rewards points. You can also transfer Marriott Bonvoy points at a 3:1 ratio, with a 5,000-mile bonus for every 60,000 points you transfer.
Based on our tests, Amex, Bilt, Capital One, Chase, Wells Fargo and Citi transfers should post almost instantly. However, our test transfer from Marriott took three days to arrive in our Flying Blue account. Because of this, points and miles from the other providers listed are your best bet if you hope to book right away.
