The incredible shrinking airline seat
Consultants are of course painfully aware of the awfulness of flying. The fact that airlines seats have become smaller and more uncomfortable over the last 50 years will not then come as any surprise.
What was surprising was the fact that airlines may only be part of that problem. Airline seat widths, pitch have apparently declined ~10% over the last ~50 years, while (ahem) our seats / weights have increased by ~20% over the same period.
