For some reason the site seems to be offline at the moment. Once it comes back up, I believe you will find more information at the following link, downloadable in spreadsheets by Year rather than Quarter...
You will find 4 tables for each calender year:
- Air Carrier Detail by Airport (Total Passengers, Average Fare, Revenue, RPMs, Avg Nonstop Distance, and Passenger Mkt Share)
- Fare Data by Airport (# of City-Pairs, Passengers, Revenue, Yield, and Avg Nonstop Trip Length; further sub-categorized into Short/Long Haul)
- Airport-Pair Detail (Airport-Pair, Density, Competitors, Low-Fare/Non-Low-Fare, Zero-Fared Pax, Total Pax, Revenue, RPMs, and Nonstop Distance)
- Airport-Pair by Carrier (Airport-Pair, Carrier, Mkt Share, Low-Fare/Non-Low-Fare, Zero-Fared Pax, Total Pax, Revenue, RPMs, Nonstop Distance, and Density)
