Delta Air Lines and US Airways made the Federal Aviation Administration a counteroffer Monday in hopes of getting approval for their blockbuster swap of assets at New York's LaGuardia and Washington, D.C.'s Reagan National airports.
But the two carriers' offer falls short of the demands made last month by FAA officials. The FAA has jurisdiction over the assets swap because it involves transferring ownership of "slots," which are time-specific landing and take off rights, at two of the USA's most congested airports. Only a handful of U.S. airports are slot-limited.
