When does SAS release EuroBonus award seats?

The rolling edge is 328 days before departure, not 330. The furthest ahead we have ever seen a EuroBonus seat appear is 343 days. But the far edge is not where most seats live: half of all Business award seats open within 52 days of departure, and 34% open within the last month. Measured over 53 days of continuous observation, ending 17 Aug 2026.

Is it really 330 days?

Nearly. SAS’s own website says award seats are released up to 330 days before departure, and the figure is repeated everywhere. What we measure is a rolling window of about 328 days: for twenty consecutive days in July the furthest bookable date moved forward by exactly one day, every day. Occasional seats appear beyond it — 343 days is our record — but they are outliers, not the edge.

We can be confident this is SAS’s limit rather than ours because we look 364 days ahead. If seats existed at 350 days out, we would have seen them.

Why the calendar looks empty eleven months out

Because two different horizons get confused. SAS loads its flight schedule about 358 days ahead, but award seats only reach 328. That leaves roughly 30 days at the far end of the calendar where the flight exists and can be bought with money, but never with points. If you have been checking the furthest dates and finding a wall of nothing, that gap is the reason.

How far in advance do seats actually open?

This is the part that contradicts the usual advice. Booking the moment the calendar opens is close to backwards for SAS’s own metal — the seats mostly are not there yet. Business has a median of 52 days before departure, Premium Economy 67 and Economy 59.

Based on 1,498 Business openings we watched happen. Fifty-three days of observation cannot properly measure something that occurs ten months before a flight, so the last row is a floor rather than a ceiling — see methodology.

Is there a time of day SAS releases seats?

No. The folk knowledge says midnight local time; we tested it and it does not hold. Counting when seats appear proves nothing on its own, because it mostly measures when anyone is looking — so we compared it against when seats disappear, which runs through the same checks at the same rhythm. If SAS loaded inventory at a particular hour, appearances would spike where disappearances do not. Across all 24 hours and all seven weekdays, the two move together. There is no hour to set an alarm for, and no best day of the week.
