The IPAC is comprised of two sub committees: IPAC Passenger and IPAC Cargo. These committees work with the Prorate Agent on technical and administrative matters relating to interline revenue proration. The committees oversee working groups that have been established to advise and make recommendations on the editorial content of the Prorate publications, and improvements to the proration process. The IPAC is elected during the General Prorate Meeting (GPM).

Areas of Activity

The IPAC works with the Prorate Agent on:
    • Administrative matters relating to prorate
    • Technical matters
    • Interpretive matters relating to prorate
    • Bringing clarity to the existing Prorate Agreements
    • Improvements to the proration process

The IPAC advises the Prorate Agent over information relating to proration to be forwarded to the Signatories:

    • Reviews and filters information to ensure that the appropriate level and volume of information reaches the Signatories
    • Recommends the formation of working groups to analyze specific issues, and oversees their progress to ensure that benefit and value is being delivered by their work.
    • Working group reports are reviewed at each IPAC meeting

The IPAC oversees General and Special Prorate Meetings:

    • Selects location for meetings
    • Drafts and submits papers to Signatories.
    • Establishes the sequence according to which papers will be presented
    • The IPAC can request that Special Prorate Meetings or additional General Meetings be held at any time
    • Guides the Prorate Agent in making decisions on protocol matters

The IPAC can call for Mail vote: it can request that a mail vote be held at any time.

The IPAC Recommends changes to the Multilateral Prorate Agreements (MPAs): it makes recommendations to General or Special Prorate Meetings, or, via mail, votes concerning proposed changes to the MPA.

The IPAC can play a dispute resolution role:

The MPA-Passenger and MPA-Cargo provides that in the event of a dispute caused by conflicting interpretations of the rules therein which is not being settled between carriers, such dispute may be directed to the Prorate Agency by the airlines involved requesting an informal interpretation should they fail to reach a bilateral agreement. On receipt of such request the Prorate Agency in consultation with the IPAC will try to settle the dispute by correspondence and decide whether or not an informal interpretation will be issued and published in the PMP (Prorate Manual Passenger). Should an informal interpretation be issued, it will be published in the PMP and will be placed on the Agenda of, and be subject to ratification by, the next Prorate Meeting

The IPAC helps clarify Prorate Meeting Decisions. Should application of any decision taken at a Prorate Meeting prove to be not achievable in practice or disruptive to the production of the PMP, the following procedures shall apply:

    • The IPAC shall resolve such matters by majority vote and shall advise the Prorate Agency
    • The clarification shall be published as an Interpretation in Section E
    • The issue will automatically be included in the Agenda for resolution at the next Prorate Meeting. The clarification will be published in the PMP unless/until rescinded or modified at a Prorate Meeting
