Data has shown that GDP is the closest guide to air travel growth. Here is an example of the research. ICAO also offers some valuable charts backing this up.
This is all great, but what happens as traffic growth continues? There isn’t an airport with perpetual construction. However, in almost every case, that construction is not adding runway capacity. This is not unique to the United States. The poster child for this problem is London Heathrow. Airport capacity is a real issue at Heathrow and is increasing at other mega hubs.
Co-Founder AirInsight. My previous life includes stints at Shell South Africa, CIC Research, and PA Consulting. Got bitten by the aviation bug and ended up an Avgeek. Then the data bug got me, making me a curious Avgeek seeking data-driven logic. Also, I appreciate conversations with smart people from whom I learn so much. Summary: I am very fortunate to work with and converse with great people.
