Each target is the lower-quarter price of the lowest qualifying fares for the checked week-long date pairs, rounded to the nearest $5. The midpoint is their median; neither is a historical market average. Shorter journeys means ≤1 stop · ≤12h out / ≤12h back; overnight arrivals allowed. Airline prices are the airline’s own fare on Google Flights for the same flights; Axel-exclusive prices need no Membership. Check bags and change rules on your fare. Airports covered: SAL → BOS.
