I fly mostly TPACs and usually don't get to choose my carrier because the company policy is lowest fare. So I focus on trying to keep everything *A at a minimum. However I would say in general that there is a huge difference in overall attitude about customer service between the American carriers and the Asian carriers. So when I have to book a UA flight, I always cringe and set my expectations very low because I know what is in store for me. If I get to book OZ or NH or SQ (which is rare) I feel like I just won the lottery
