US airline seat densification Part 1: Alaska, JetBlue and Southwest strike a delicate balance

Any number of US airlines are in the midst of, or have recently completed, reconfigurations to increase seating density on their aircraft in an effort to drive additional revenue at a relatively low cost. As capacity creeps up in the domestic market place, airlines often reference their aircraft densification programmes as efficient capacity expansion.

Three US airlines viewed as some of the most consumer friendly - JetBlue, Alaska and Southwest - have all opted to add seats to their respective narrowbody fleets. Those airlines walk the fine line of adopting strategies to bolster revenue while ensuring that passenger goodwill remains intact. Few consumers enjoy less legroom.

The revenue potential of densifying aircraft for most airlines is too beneficial to pass up, reflecting the balance of appeasing investors and working to create a still comfortable travelling experience. It is a scenario whose prevalence will grow as both passengers and shareholders become more vocal in their demands.
