United Airlines pressured to make network changes as its revenue growth remains sluggish

United Airlines' prolonged underperformance in revenue generation relative to its US network airline peers has led to growing questions about United's management of its network, and if certain hubs should be eliminated altogether.

Recently the performance of United's Dulles hub has come under scrutiny as its proximity to the airline's gateway at Newark Liberty seemingly diminishes the importance of Dulles in United's overall network.

The latest bout of criticism for United reflects growing industry curiosity and impatience regarding a timeframe of when the airline could possibly close the revenue performance gap relative to its US peers. Until United begins to show solid signs of improvement, every detail of the airline's network and operations will continue to be scrutinised, and the criticism is likely to continue.
