EuroBonus route intelligence
SAS award seats to Boston
SAS flies to Boston from its Scandinavian hubs (CPH, ARN, OSL), and we log every EuroBonus award seat on the route continuously. Over the last 8 days we recorded 731 award-space openings across all cabins, 103 of them in Business. Business space typically appears 212 days before departure (middle half of openings: 43–298 days out). Once open, a Business seat survives a median of 21 hours; 58% of the disappearances we observed happened within 24 hours.
