How United Is Chasing Revenue by Adding More Premium Seats

By adding a new premium-heavy configuration, United Airlines will be increasing operational complexity. It is hoping it can offset that with increased revenue.
 Some airlines are willing to take chances on multiple configurations. United Airlines is apparently joining the group with a special interior to chase premium revenue in key business markets.Rather than putting a standard configuration in its Boeing 767s – United generally has 30 business class seats and 184 in economy – the airline soon is likely to unveil a new product with 46 seats in business, 22 in premium economy, and only 99 in economy.
