The Long Beach city council is set to approve an agreement today over control of slots at LGB. The settlement calls for JetBlue to return 5 slots with 3 going to AA and 2 going to Alaska. If at any time before 1/1/2009 AA or AS stops using their new slots they immediately will go back to JB.
The agreement also calls for new noise studies at LGB to determine if cumulative noise levels exceed that allowed in the airport's "noise budget". If they do not, then additional slots above the 41 mainline limit may be created.
The noise budget was a key part of the original LGB noise agreement. A cumulative allowable noise level was determined. Then using average noise levels caused by aircraft at the time (1980s) it was decided that 41 slots was the maximum that could operate without exceeding the "budget".
If the city of Long Beach approves the agreement today it then goes to the FAA for final approval.
