Major carriers that commonly operate BOS–MUC routes or codeshares in August include Lufthansa, United, Delta, and partner airlines. Lufthansa may offer the most direct connectivity and consistent service for Munich-bound passengers, often with baggage included on transatlantic fares; U.S. legacy carriers can provide competitive pricing and loyalty program connectivity via hub connections. When comparing airlines, review fare class inclusions (seat selection, checked baggage), onboard service (meal service and Wi-Fi), and alliance benefits for award travelers. For August travel, check each carrier’s schedule reliability and look for bundled fares that include baggage to avoid extra fees.
