American’s pilots claim to be unhappy.
This is important because although American and US Airways have merged, and from a customer-facing standpoint are a single carrier (albeit with very different legacy products that the airline is slow to update), work groups are not yet on the same system and pilots do not yet have a single seniority list that will allow the airline to function as one.
There are still planes attached to destinations and crews, and that prevents American from matching the right equipment to the right route and optimize aircraft so that expensive capital equipment gets the most efficient use possible as well. In other words, many of the merger’s promised synergies remain on the table.
