I'm not sure how "responsibility" for bags getting there works when you are traveling on multiple airlines--who is ultimately responsible (and supposed to handle your baggage claim if lost)?
All Member Carriers of the
International Air Transport Association (IATA) follows Resolution 302 which governs baggage allowances and charges, using a concept of the Most Significant Carrier (MSC) to determine whose baggage rules apply for the itinerary. The final transporting carrier will be responsible for any delayed or mishandled luggage claims so in your case DL to AS to UA would leave United as the liable carrier should something go pear shaped in-transit with your baggage.
