Dear Mr. Wuerfer:

This letter is to inform you that we have granted your petition to extend Exemption No. 10064, as amended. It explains the basis for our decision, describes its effect, and lists

the conditions and limitations.

The Basis for Our Decision

By letter dated March 18, 2016, you petitioned the Federal Aviation Administration (FAA) on behalf of Allegiant Air, LLC (Allegiant Ai r) for an extension of Exemption No. 10064, as amended. That exemption from §§ 121.623(a) and (d), 121.643, and 121.645(e) of Title 14, Code of Federal Regulations (14 CFR) allows Allegiant Air to conduct supplemental operations within the 48 contiguous United States and the District of Columbia using the flight regulations for alternate airports as required by § 121.619 and the fuel reserve regulations as required by § 121.639 that are applicable to domestic operations.

In your petition, you indicate that there has been no change in the conditions and reasons relative to public interest and safety that were the basis for granting the original exemption.

The FAA has determined that good cause exists for not publishing a summary of the petition in the Federal Register because the requested extension of the exemption would not set a precedent, and any delay in acting on this petition would be detrimental to Allegiant Air.2

Our Decision

The FAA has determined that the justification for the issuance of Exemption No. 10064, as amended, remains valid with respect to this exemption and is in the public interest. Therefore, under the authority provided by 49 U.S.C. §§ 106(f), 40113, and 44701, which the FAA Administrator has delegated to me, Allegiant Air, LLC is granted an extension of its exemption from 14 CFR §§ 121.623(a) and (d), 121.643, and 121.645(e) that allows Allegiant Air to conduct supplemental operations within the 48 contiguous United States and the District of Columbia using the flight re gulations for alternate airports as required by § 121.619 and the fuel reserve regulations as required by § 121.639 that are applicable to domestic operations, subject to the following conditions and limitations.

2. Allegiant Air must ensure that its aircraft dispatchers hold aircraft dispatcher certificates issued under subpart C of part 65 and are properly qualified under part 121, subpart P, before permitting those persons to serve in operations conducted under this exemption.

3. Allegiant Air must conduct its supplemental operations under this exemption--

(a) Within the 48 contiguous United States and the District of Columbia; and

(b) Except as required in § 121.637 for unlisted airports, or to, from, or between those regular, provisional, refueling, and alternate airports listed in its operations specifications or listed in a separate current listing, that listing is referenced in its operations specifications and is authorized by the
