I fly frequently both KLM and SAS. On which program should I collect points?

If you fly a lot on both KLM and SAS, the most flexible choice is to concentrate on Air France‑KLM Flying Blue, while keeping your EuroBonus account active for any status‑related perks you already enjoy.

Why Flying Blue is usually the better primary program

• It is the shared SkyTeam program for both airlines, so you can earn and redeem miles on any KLM or SAS flight  Economy Class & Beyond
• Flying Blue accepts points from all major U.S. transferable currencies (Amex, Chase, Citi, Capital One, Bilt) and frequently runs transfer bonuses, making it easy to top‑up your balance  View from the Wing God Save the Points Your Mileage May Vary
• The program offers free stopovers on one‑way awards and monthly Promo Rewards that start at low mileage levels, which can be especially valuable for frequent transatlantic travelers  View from the Wing Your Mileage May Vary
• You can use Flying Blue miles for a wide range of award options, including business‑class seats on Air France, KLM, Delta and other SkyTeam partners, often with lower surcharges  God Save the Points Your Mileage May Vary

When to keep EuroBonus active

• EuroBonus members automatically receive SkyTeam elite benefits (SkyPriority, lounge access) once SAS joins SkyTeam, and higher tiers (Silver, Gold, Diamond) map to SkyTeam Elite/Elite Plus status  One Mile at a Time
• If you already hold EuroBonus status, you can continue to enjoy those tier perks on SAS and other SkyTeam flights without needing to re‑qualify  One Mile at a Time
• EuroBonus points can be earned only by flying SAS (no major U.S. transfer partners), so they are less useful for topping up balances, but they still work for redeeming SAS‑operated flights  FrequentMiler

Practical approach

1. Primary accrual: Use Flying Blue for most of your KLM and SAS flights to benefit from the broader earning options and richer award inventory.
2. Status maintenance: Keep your EuroBonus account if you have Silver or higher status, so you retain SkyTeam elite privileges on SAS flights.
3. Redeeming: For award bookings, prioritize Flying Blue miles (more partners, promo rewards, stopovers). Use EuroBonus miles only for SAS‑specific awards where Flying Blue availability is limited.

By focusing on Flying Blue while preserving any existing EuroBonus status, you get the best of both worlds: maximum earning flexibility and the elite perks you may already have with SAS.
