Moron. You increase the number of people on each airplane. Bigger airplanes.
Ain't that simple. "Bigger airplanes" assumes that the longer runways that can accommodate those larger planes aren't already maxed out. In the event that there is room to accommodate those planes, the airport has to account for new wake separation procedures. There's also the issue of whether the markets served by the airline are appropriate for larger planes. Finally, larger planes are in many (but not all) cases louder than smaller planes, and that results in environmental issues that are similar to those building new runways.
At best, "Bigger airplanes" is a stop-gap solution.
