Do Airline Mergers Cause Fare Hikes Between Hubs?
With a handful of high-profile airline mergers occurring over the last several years, many flyers may be wondering what effect they've had on fares — specifically between former hubs due to decreased competition. TPG Contributor JT Genter explores the data below.
The last decade has seen tremendous consolidation among the US-based airlines: Delta merged with Northwest, United with Continental and — most recently — American Airlines merged with US Airways.
The fear among travelers and the Antitrust Division of the US Department of Justice was that these mergers would reduce competition and increase fares. After all, in the six years before these mergers began, dozens of airlines were found to be illegally fixing prices — leading to $1.7 billion in fines. But, the airlines successfully convinced their regulators that these mergers were necessary and wouldn't result in price-gouging the traveling public.
So, how have things ended up?
As you can see, there's a bit of a climb in average airfares since the mergers began. However, when you factor in the state of the economy through this time period, there really isn't a meaningful upward trend that could be attributable to the mergers.
Does this conclusion not feel right to your experience? Well, this chart is simply presenting average airfare across the country. As they say, your mileage may vary. If you look at fare changes city by city, there's a lot of variation.
Aviation Guru pulled the average fare data for flights between current and former hubs to study the direct impact of reduced competition. For example, would the consolidation of Delta and Northwest cause average fares to increase between Atlanta (ATL-Delta hub) and Minneapolis (MSP-Northwest hub)?
Increase (decrease) in Delta hub-to-hub fares from 2010-2015. Data complied by Aviation Guru from BTS TranStats
As you can see, hub-to-hub routes greatly increased after the Delta merger was finalized at the end of 2009. On average, these twelve routes increased ~27% from 2010 to 2015. The large outlier is clearly flights between Memphis (MEM) and ATL, which soared nearly 90% from 2010 to 2015. Only one of these twelve routes decreased post-merger: MEM-New York City (JFK).
So, what about the United-Continental merger?

While the merger was approved by regulators and shareholders in 2010, the merger wasn't completed until late 2011. Interestingly, 2010-2012 showed significant fare increases among the hubs — soaring ~28% on average in just two years.
However, once the merger was completed, fares between United and Continental hubs have returned closer to 2010 levels, with the average increase over five years being under 10%. Interestingly, if you use 2011 — instead of 2010 — as the base year, average fares between hubs dropped ~10% on average.
Bottom Line
While airfares haven't dramatically increased nationally after the big three airline mergers of the last decade, there have been some big winners and losers from the airline mergers.
On average, airfares between former Delta and Northwest hubs increased substantially — much more than the national average — demonstrating that the Delta-Northwest merger wasn't good for hub-based flyers.
However, airfares between United and Continental hubs have seen much more modest increases over the last five years, and the fares have actually decreased on average over the last four years.
