Opinion for the Court filed by Circuit Judge SILBERMAN.
United Airlines, Inc. appeals the district court order directing arbitration of a collective bargaining dispute between it and the Association of Flight Attendants (AFA). We affirm.
I.
The facts are not disputed. UAL Corporation, which is the sole owner of United Airlines, acquired all the shares of Air Wisconsin. UAL maintained the two airlines as separate subsidiaries. The Association of Flight Attendants represents the flight attendants at both Air Wisconsin and United pursuant to National Mediation Board (NMB or Board) certifications. The AFA demanded that the Air Wisconsin flights be staffed only by flight attendants on the United Air *917 lines System Seniority List under the terms and conditions of the AFA-United collective bargaining agreement, notwithstanding the AFA-Air Wisconsin collective bargaining agreement. United refused, and the AFA filed a grievance.
A 1986 side letter agreement between the parties, the source of United’s purported contractual obligation, provides:
Except as specifically provided in [another side letter agreement], neither UAL, Inc., United Airlines nor a successor, assign, or subsidiary thereof (hereinafter referred to as the “Company”), will, if such entity has a controlling interest, whether acting individually or jointly with any of the above entities, conduct any commercial flight operations of the type historically performed by United Airlines Flight Attendants, unless it performs such work with flight attendants on the United Airlines System Seniority List. Such flying shall be performed in accordance with the terms and conditions of the existing agreement or any other applicable agreement between the Company and the Union.
This scope clause agreement was incorporated verbatim into, and runs concurrently with, the posb-1986 AFA-United collective bargaining agreement, which became effective September 1, 1991, and is not amendable until March 1, 1996. United refused to process this grievance, asserting that the AFA’s claim fell within the Board’s exclusive jurisdiction. The AFA sought an order from the district court compelling United to arbitrate its scope clause claim before the United-AFA system board of adjustment. Summary judgment was granted in favor of the AFA
II.
The parties disagree over the proper characterization of their dispute. AFA claims that it is a “minor” dispute while United argues that it is a representation dispute. The Railway Labor Act (RLA) provides different procedures for the resolution of “minor” disputes and representational disputes.

“Minor” disputes, which “‘relate[] either to the meaning or proper application of a particular provision’” of a collective bargaining agreement,
Consolidated Rail Corp. v. Railway Labor Executives’ Ass’n,
United argues that the district court lacked subject matter jurisdiction over the AFA’s scope clause claim because the requested order encroaches upon the exclusive jurisdiction of the Board. The scope clause dispute, it is argued, raises a representation
*918
issue because the “NMB must first resolve the question of whether previously separate carriers have in fact combined to form a single carrier and whether the employee groups at each carrier should therefore be combined.” An arbitrator’s resolution of this issue would infringe upon the “continuing right of a majority of employees within each ‘craft or class’ at each carrier to determine whether, in the future, they desire to be represented by a particular union, or at all.” United points out that federal courts, including our circuit, have addressed situations where an airline carrier has been acquired by another airline in which the union representing employees of the acquiring company attempts to enforce a scope agreement which requires the application of its collective bargaining agreement to the corresponding class of employees of the acquired carrier. And in those cases courts have concluded that the scope clause dispute implicates representation issues which can only be resolved by the NMB.
See, e.g., Flight Eng’rs’ Int’l Ass’n v. Pan American World Airways, Inc.,
We think, as did the district court (and AFA), that the cases United relies on are distinguishable. It is rather obvious that if two airlines merge and their employees in the same jobs are represented by different unions the federal courts lack jurisdiction over collective bargaining claims because a representation issue is necessarily implicated.
See, e.g., Air Line Employees v. Repub-lie, Inc.,

In our case, both groups of employees are represented by the AFA so there is no question as to the identity of the exclusive representative. The AFA contends that fact is dispositive of the case; as the union puts it, representation issues are essentially “who” questions — which union, if any, will represent employees. United points out, however, that as a corollary, or precondition of such a determination, the NMB must determine the appropriate craft or class, or grouping of employees, to be represented by a union. Nor is such a Board craft or class designation only made at the time an election is to be held. United points to a recent NMB ease in which the Board determined the appropriate class or craft after a merger of four airlines, all represented by the same union.
See U.S. Air Express,
The case comes down then to the question whether the district court’s order interferes legally or practically with the Board’s capacity,
at any time
— whether in connection with
an
election or otherwise — to determine whether the flight attendants at both airlines constitute one or separate crafts or classes. We do not think so. The Board itself has stated “that carriers and labor organizations are free to include any employee classifications under a voluntary recognition agreement, [but] once a representation dispute is brought before the Board ... [such an agreement] ... cannot dictate the Board’s craft or class findings.”

For the preceding reasons, we hold that the AFA’s claim must proceed to arbitration.
Notes
. A third category of disputes, not at issue in this case, are "major” disputes which have to be resolved through an elaborate and lengthy procedure of bargaining and mediation.

. The court in Texas Int'l Airlines reasoned that enforcement of the contract would result in a situation where the union retained its bargaining responsibilities despite the NMB "rule” that upon a merger of two airlines all certifications are extinguished by law. Allowing the union to remain de facto the representative of its pre-merger members would frustrate the NMB goal behind this "rule” of avoiding "uneven representation, duplication of effort, and confusion.” Id. at 163 (citation omitted). While not taking a position on the validity of this reasoning, a facet of Texas Int’l Airlines that Delta Air Lines and USAir did not focus on, the enforcement of the side letter agreement would not result in the frustration of any NMB policy as far as we can ascertain.
