AA is gilded around the edges with some really nice premium features, but fundamentally fails at the points that matter most to good airlines (operational reliability and customer service/employee quality).

There are a few premium aspects that I wish UA would adopt, but United runs a good operation that is almost always on time, and that’s what matters most to me.

Flagship First dining and showers in most clubs are great, but don’t matter much when the entire departure board is delayed.
