An air carrier may end, suspend, or reduce air transportation to an eligible place below the level of basic essential air service established for that place under section 41733 of this title only after giving the Secretary of Transportation, the appropriate State authority, and the affected communities at least 90 days’ notice before ending, suspending, or reducing that transportation.

If at the end of the notice period under subsection (a) of this section the Secretary has not found another air carrier to provide basic essential air service to the eligible place, the Secretary shall require the carrier providing notice to continue to provide basic essential air service to the place for an additional 30-day period or until another carrier begins to provide basic essential air service to the place, whichever occurs first.

If at the end of the 30-day period under subsection (b) of this section the Secretary decides another air carrier will not provide basic essential air service to the place on a continuing basis, the Secretary shall require the carrier providing service to continue to provide service for additional 30-day periods until another carrier begins providing service on a continuing basis. At the end of each 30-day period, the Secretary shall decide if another carrier will provide service on a continuing basis.

If an air carrier receiving compensation under section 41733 of this title for providing basic essential air service to an eligible place is required to continue to provide service to the place under this section after the 90-day notice period under subsection (a) of this section, the Secretary shall provide the carrier with compensation sufficient—

(1) to pay for the fully allocated actual cost to the carrier of performing the basic essential air service that was being provided when the 90-day notice was given under subsection (a) of this section plus a reasonable return on investment that is at least 5 percent of operating costs; and

(2) to provide the carrier an additional return that recognizes the demonstrated additional lost profits from opportunities foregone and the likelihood that those lost profits increase as the period during which the carrier is required to provide the service continues.

If the Secretary requires an air carrier providing basic essential air service to an eligible place without compensation under section 41733 of this title to continue providing that service after the 90-day notice period required by subsection (a) of this section, the Secretary shall provide the carrier with compensation after the end of the 90-day notice period that is sufficient—

(1) to pay for the fully allocated actual cost to the carrier of performing the basic essential air service that was being provided when the 90-day notice was given under subsection (a) of this section plus a reasonable return on investment that is at least 5 percent of operating costs; and

(2) to provide the carrier an additional return that recognizes the demonstrated additional lost profits from opportunities foregone and the likelihood that those lost profits increase as the period during which the carrier is required to provide the service continues.

When the Secretary requires an air carrier to continue to provide basic essential air service to an eligible place, the Secretary shall continue to make every effort to find another carrier to provide at least that basic essential air service to the place on a continuing basis.

If an air carrier, providing basic essential air service under section 41733 of this title between an eligible place and an airport at which the Administrator of the Federal Aviation Administration limits the number of instrument flight rule takeoffs and landings of aircraft, provides notice under subsection (a) of this section of an intention to end, suspend, or reduce that service and another carrier is found to provide the service, the Secretary shall require the carrier providing notice to transfer any operational authority the carrier has to land or take off at that airport related to the service to the eligible place to the carrier that will provide the service, if—

(1) the carrier that will provide the service needs the authority; and

(2) the authority to be transferred is being used to provide air service to another eligible place.

In determining what is basic essential air service and in selecting an air carrier to provide such service, the Secretary shall not consider as a factor whether slots at a high density airport are available for providing such service.

If, after the date of enactment of this subsection, an air carrier commences air transportation to an eligible place that is not receiving scheduled passenger air service as a result of the failure of the eligible place to meet requirements contained in an appropriations Act, the air carrier shall not be subject to the requirements of subsections (b) and (c) with respect to such air transportation.
