Got an email survey as follow-up to my LAX-IAD flight last week. Lots of questions about service, efficiency, whether carry-on rules were enforced, TSA "courtesy and wait time" (LAX - HAHA), and so forth. The additional questions were to the point: "What reasons did you not check baggage (prioritize 1-4)", "If AA were to give 500 miles for checking bags, would you?" "If AA were to give 1000 miles for checking bags, would you?", "What would we have to do to get you to check bags"..... Very interesting. Testing incentives to get elites to check bags. Personally, incentives wouldn't do it for a variety of reasons - including TSA, time to deliver bags, and risk of losing bags when I'm on a series of one-night stands.
