Great analysis! a couple of comments:

1. the airfare inflation chart is based on the Bureau of Labor Statistics CPI which is calculated differently from the other metrics in the article; it does take into account routes popularity.

2. today’s average Economy ticket is different from the 1990s ticket: meals, seat pitch, seat selection, baggage. service changed to the point that 1990 Standard Economy is more similar to 2025 Premium Economy.
