I watched the recent swapping of airline slots between Delta Air and US Airways and between AirTran and Continental. Once upon a time, the airlines were howling when the FAA wanted to limit landing and take-off slots at La Guardia, Newark and JFK as a solution to overcrowding of the airspace. They claimed that Congress never explicitly gave the FAA the right to auction slots.

Has Congress given the airlines explicit rights to trade federal assets? And what about the consumers?

Whenever and airline executive mentions “strengthen our network,” it is code for “eliminate competition.” Hopefully, someone in the regulatory regions of the U.S. government will take a hard look at how consumers will fair under these cavalier swaps being proposed by the airlines.

So far every article I have found covering this subject has pronounced changes and the effects on the airline industry. No one has taken the time to look at these swaps from a passenger’s point of view and at the elimination of competition that many of the moves portend.

As I look at these swaps, it looks like the major airlines are working at making their fortress hubs more secure. In other words, they want to eliminate as much competition in their hubs as possible. That normally has meant that the consumers are ready to take it in the shorts with higher airfares.

Craig Jenks, who heads Airlines/Aircraft Projects Inc., also believes the swaps are “the right thing to do in the current environment.” Airlines are more worried about yield than volume now, and these moves address that concern by making them stronger in their best markets while reducing competition.

US Airways has added to their already leading position at Washington Reagan. Delta is ensconcing itself in the La Guardia and JFK airports. Delta and US Airways has also swapped coveted international routes that are normally carefully controlled by the FAA. And Continental has added to its position at its Newark hub.

The AirTran move to give up its Newark slots allows it to shut down an all-but-orphaned operation at Newark and shut their entire operation there. The increases at LaGuardia and Washington Reagan (DCA) are welcome, since they will enhance and strengthen low-cost-carrier pressure at both airports.

However, this all begs the question: Shouldn’t the FAA be controlling these slot swaps, rather than allowing the airlines to trade their positions like baseball cards?

When the FAA wanted to cap service, the airlines fought them at every step. Now that they the airlines are making moves without what seems like any serious FAA and DOT studies, it seems like our transportation watchdogs are toothless.

There is still time for the DOT and FAA to act. The slot exchange is expected to start sometime in early 2010, and the final parts of the agreements probably will not fall into place until next fall.

The least they can do is take a close look at how this will shape competition in each of the airports concerned. They need to take into consideration airline alliances as they make their assessments. It is obvious that US Airways controlling DCA and their partner United Airlines with a giant footprint at Washington Dulles smacks of coordinated power-sharing. US Airways virtual abandonment of Newark also seems to play into their coming alignment with Continental that dominates that hub.

From an international point of view, the competition for the routes in question should be reopened so those airlines who bid for the routes can compete again for the routes and the international revenue. It doesn’t seem right that airlines who once competed against each other for these routes now give them up willingly after they were selected in the public interest.

I hope someone in Washington at the DOT and the FAA is watching as the airlines make their swaps. I hope they keep the public interest uppermost in their minds as they assess the fallout of these slots. We have some time for a bit of good old government oversight.
