I think the comment that if the best score is a C grade and the worst is a D says it all. Meh! (First World Problems other people would love to have).

I must admit that AC's offerings have declined in recent years while United's have gone up and I have had ok flights on Delta in front cabins but they are all meh! and mostly get me where I want to go safely and mostly haven't had missed connections etc. All suffer from one thing or another, especially on shorter flights. Being at the bottom of the middle of the pack means AC does need to try a lot harder. All need to clean up their lounge offerings/crowding, AC its soft product, UA its hard product etc.
