Applicant states that it will not directly provide shuttle services to the public. Services under the LAX concession agreement will be provided by the members using their own fleets of vehicles. While the Commission has no objection to this arrangement, we remind Applicant that as holder of a PSC certificate it will have ultimate responsibility for ensuring satisfactory service to the public and compliance with rules and regulations applicable to passenger stage corporations as set forth in GO 158-A. In this regard, Part 7.01 of GO 158-A requires the carrier to respond within 15 days to any written complaint concerning transportation service provided or arranged by the carrier, and within the same number of days respond to Commission staff inquiries regarding complaints. It is desirable and appropriate that Xpress through its manager be responsible for responding to and resolving service complaints, notwithstanding that the service may have been provided in a vehicle operated by one of Applicant's members.
