I have been totally freezing on the last 3 American Airlines flights I have taken. During the same time frame I was comfortable on flights by United, Virgin America, and Delta. On the last flight I came prepared with a warm jacket, extra pair of wool socks, and gloves - put them all on (adding to the squeezed feeling in the seat) and was still cold. I asked flight attendant for blanket but was told they are only for First class. I was told that they would adjust the temp (I wasn't the only one who was cold) but if it the temp was raised, it didn't have much effect. Have other American Airline passengers noticed this or is it just me? It occurred to me that it may be an attempt to save money but fortunately I will soon have another choice (Virgin America) for nonstop flights from San Jose, CA to Dallas which is a frequent route for me.
