50
percent decline (real terms)
Average airfares have declined by roughly 50% in real terms since 1990, making flying more accessible to a broader population.
解説
Adjusted for inflation, the average cost of a domestic flight has approximately halved over three decades. Competition from low-cost carriers, more fuel-efficient aircraft, higher load factors, and online booking platforms have all contributed. However, base fares have been partially offset by the rise of ancillary fees. The trend has enabled billions of first-time flyers, particularly in Asia and Latin America.
