Delta Air Lines is the primary carrier offering nonstop service between Boston Logan International Airport (BOS) and Minneapolis−Saint Paul International Airport (MSP), often with multiple daily frequencies, strong on-time performance, and SkyMiles benefits. American Airlines and United Airlines frequently offer one-stop connections via their hubs (CLT, ORD, EWR), which can be cheaper but longer. JetBlue and other carriers may provide seasonal or connecting options—check codeshares and alliance partners to maximize loyalty points. For October travel, compare refundable and changeable fares, baggage allowances, and seat selection fees; Delta's nonstop convenience is balanced by occasional premium pricing, while connecting itineraries may save money for flexible travelers.
