Aрpellant Paul J. Pyles, a former Pan American Airlines pilot, appeals the district court’s dismissal of his case against United Airlines. The district court dismissed the ease on the grounds that appellant’s claims are preempted by both the Railway Labor Act (“RLA”), ch. 347, 44 Stat. 577 (1926), 45 U.S.C. §§ 151 et seq. (1988), and the Federal Aviation Act (“FAA”), Pub.L. 85-726, 72 Stat. 731 (1958) (repealed by Pub.L. No. 103-272, § 7(b), 108 Stat. 745, 1379, 1383 (1994), and replaced by provisions of 49 U.S.C.A. §§ 40101-49105 (West 1995)). We affirm.
I.
On October 23, 1990, United and Pan Am entered into an аgreement in principle whereby Pan Am would sell to United, in a two-phase transaction, the following: first, two of its Boeing 747 aircraft and some ground facilities, and second, some of its European routes and equipment used to service those routes. A final agreement for the transaction (the “Phase Two Agreement”) was signed on November 14, 1990. To address concerns over potential job losses at Pan Am as а consequence of the route and aircraft sale, the Phase Two Agreement provided that:
[United] shall exercise its best efforts to take a reasonable number of qualified and current B747 flight crew members from [Pan Am’s] seniority list following the In-, terim Closing or the Closing, as the ease may be. [United] will utilize its normal hiring procedures and standards, and will consider employing only flight crew members who are currently flying the European operation, determined by [United] to bе pilot-qualified, and pass [United’s] flight medical examination.
Phase Two Agreement § 5.9(g) (emphasis added).
The Air Line Pilots Association (“ALPA”) maintained a local at both United (the “UAL-ALPA”) and Pan Am (the “PAA-ALPA”), and represented pilots of each airline in collective-bargaining negotiations. The agreement called for UAL-ALPA and PAA-ALPA to negotiate and then provide United, by December 1,1990, with an agreed number of Pan Am crews to be transferred to United. Phase Two Agreement § SNgXii). 1 Failure to do so would result in United’s being free from any obligation to hire any Pan Am crews. Unable to reach an agreement, the union locals were subsequently sent to arbitration pursuant to a resolution passed by the Executive Committee of ALPA International. 2 On February 8, 1991, the arbitrator rendered his decision, reduced to a written award on March 27, which concluded that forty-two Pan Am 747 flight crew members should be transferred to United.
While these events transpired, United еntered into negotiations with ALPA. On February 4, 1991, they entered an agreement (the “letter of agreement”) that established a framework for the impending crew transfers. The letter of agreement discussed the general manner in which integration of the Pan Am crews into’ United operations would proceed, the benefits and compensation the transferred crews would be entitled to receive, and the selection criteria for transfer. In addition, the agreement admonished that transferring crews would have to “pass a United pilot physical examination” and “otherwise satisfy all of United’s normal pilot hiring criteria.” Letter of Agreement, Attachment A.
Appellant’s seniority was such that he qualified to be among the group slated for transfer to United. He therefore submitted to United’s physical examination on April 1, 1991. Pyles claims hе was told that he failed this physical examination because radial ker-atotomy surgery had been performed on his *1049 eyes in 1986. On that basis, he alleges that United refused to hire him and officially denied him employment on April 8. Having been denied a job, Pyles brought this action in the district court.
Pyles had three state-law claims pending in the district court when the order dismissing the ease was entered on July 21, 1993. 3 Has first claim was for breach of the route purchase agreements between Pan American and United. The second alleged breach of the letter of agreement between United and UAL-ALPA Pyles claimed to be a third-party beneficiary to these agreements. Pyles’ final claim alleged that United tor-tiously interfered with the business relationship between Pyles and Pan Am.
II.
We consider first appellant’s first and third counts. Section 11.5 of the Phasе Two Agreement, entitled “No Third Party Beneficiary,” states that
[njothing herein expressed or implied is intended to or shall be construed to confer upon or give to any person or corporation other than the parties hereto and their successors or permitted assigns any rights or remedies under or by reason of this agreement.
Phase Two Agreement § 11.5. Because he is not a party to the agreеment and because the agreement specifically precludes third-party beneficiaries, appellant has failed to state a claim in his first count. See Fed.R.Civ.P. 12(b)(6).
Appellant’s third count, for tortious interference, likewise fails to state a claim. The complaint lacks a sufficient factual predicate to substantiate how United tortiously interfered with Pyles’ business relationship with Pan Am. Under Florida law, Pyles must prove the following in order to recover for tortious interference with a business relationship:
1.the existence of a business relationship under which Pyles has legal rights;
2. knowledge by United of such relationship;
3. an intentional and unjustified interference with the relationship by United; and
4. damage to Pyles.

III.
Most of the provisions of the RLA apply to labor relations in the airline industry.
See
45 U.S.C. § 181. The RLA has established a framework for the resolution of disputes between air carriers and their employees that “grow[] out of grievances, or out of the interpretation or application of agreements concerning rates of pay, rules, or working conditions.” 45 U.S.C. § 184. The distinguishing feature of such a dispute, termed a “minor dispute,” is that “the dispute may be conclusively resolved by interpreting the existing [collective-bargaining] agreement.”
Consolidated Rail Corp. v.
*1050
Railway Labor Executives’ Ass’n,
The Supreme Court recently revisited its standard for preemption of claims by the RLA in
Hawaiian Airlines, Inc. v. Norris,
- U.S. -,
Applying the standard set forth in Hawaiian Airlines, we find appellant’s second claim, alleging breach of the letter of agreement between United and UAL-ALPA, preempted by the Rahway Labor Act. 5 The letter, in its first paragraph, indicates that it is “entered into in accоrdance with the provisions of the Railway Labor Act.” Moreover, it is, by its terms, a modification of the collective-bargaining agreement (“CBA”) between United and its employees; to interpret the letter is thus to interpret a portion of the CBA. 6 Appellant’s second claim asserts no rights that are independent from the CBA. His claim is rooted in the CBA itself and the alleged breach thereof. Because the CBA is the оnly potential source of any rights he may have to employment with United, one must interpret the CBA to determine what those rights are.
Appellant nonetheless attempts to elude preemption by maintaining that his case falls outside the coverage of the RLA because he was never employed by United. The term “employee,” as defined in the RLA, includes “every person in the service of a carrier (subject to its continuing authority to supervise and direct the manner of rendition of his service) who performs any work defined as that of an employee.” 45 U.S.C. § 151, par. Fifth. It is undisputed that Pyles was an employee of Pan Am prior to the route and crew transfers and continued, albeit only for a short time, to be employed by Pan Am thereafter. Appellant contends, however, that the RLA is inapplicable and does nоt bar his claim because he was never an employee of United. We disagree.
In construing the term “employee,” we first look to the plain meaning of the provision. Pyles never “perform[ed] any work defined as that of an employee” for United and was certainly never subject to United’s supervisory authority. Therefore, upon a cursory review, the language appears to support appellant’s position.
See Air Line Pilots Assoc. v. United Air Lines, Inc.,

*1051
F.2d 886, 913 (7th Cir.1986),
cert. denied,
To ascertain the intent behind a definitional provision that applies throughout the RLA, we look to the substance of the Act as a whole. Section 151a of the RLA indicates that a central purpose of the RLA is “to prоvide for the prompt and orderly settlement of all disputes growing out of grievances or out of the interpretation or application of [CBA] agreements.” 45 U.S.C. § 151a. A primary justification for the establishment of grievance machinery is the desire of Congress to have labor agreements interpreted in a uniform manner.
See Pennsylvania R.R. v. Day,
Our belief is reinforced when we examine the factual context from which this case arose. To support his position, appellant relies on
Nelson v. Piedmont Aviation, Inc.,
*1052 We believe this is precisely the sort of dispute that belongs, before a system board of adjustment. During all relevant times, Pyles remained in the employ of an airline. The agreements contemplаted just such a direct.transfer of employees from one airline to another. In fact, Pyles’ entire claim is premised on his 'allegation that he was contractually entitled, pursuant to a modified CBA, to transfer to United. We thus regard Pyles as an employee as defined by, and thus, within the scope of, the RLA.
IV.
Appellant contends that if we hold that his claim is preempted, we shall leave him remediless becausе he would lack a forum in which to present his case. We cannot agree. While the RLA expresses a clear preference for arbitration of minor disputes, it is equally clear that it reflects a strong congressional interest in seeing that employees are not left remediless.
See Capraro v. United Parcel Serv. Co.,
Appellant should first have attempted to pursue his grievance before a system board of adjustment individually (or with counsel) and without any union assistance.
See Stevens v. Teamsters Local 2707,
Alternatively, if the pursuit of an administrative remedy became truly impossible, appellant could have sought to demonstrate that he qualified for an exception to the exhaustion requirement. Employees can avail themselves of remedies in federal court without exhausting administrative remedies if their employer repudiates the grievance machinery or thе union wrongfully refuses to
*1053
process a grievance.
See Vaca v. Sipes,
Finally, appellant could have brought suit against his union. A union’s failure to represent properly an employee may lead to a claim in federal court for breach of the union’s duty of fair representation.
See Steele v. Louisville & N.R.R.,
As the above makes apparent, appellant had many options available to ensure that his case was heard, either through arbitration before a system board or in a federal court. Unfortunately, he chose none of those optiоns.
AFFIRMED.
Notes
. UAL-ALPA and PAA-ALPA were also responsible for reaching an agreement by December 1, 1990, which provided for name and seniority integration of the transferred pilots as well as “other contractual matters deemed by [United] necessary to render offers of employment operationally viable.” Phase Two Agreement § 5.9(g)(iii).
. The resolution also requested that United extend its deadline for submission of proposed transfers for a reasonable time in light of the arbitration.
. A fourth count, for tortious interference with a business relationship between Pyles and ALPA, was dropped.
. Because we dismiss Pyles’ first and third counts pursuant to Rule 12(b)(6), we need not decide whether these claims are also preempted by the RLA and FAA.
. Because we decide that this claim is preempted by the RLA, we need not reach the issue of FAA preemption.
. One must also interpret other provisions of the CBA in order to interpret properly the letter of agreement. For instance, Attachment A of the letter of agreement uses terminology such as "United's normal pilot hiring criteria.” To discern what those criteria are, one must interpret the CBA, which governs United's hiring procedures.
. The Supreme Court performed a similar analysis in
Day,
[a]ll the considerations which led Congress to entrust an expert administrative board with the interpretation of collective bargaining agreements are equally applicable when, as here, the employee has retired from sеrvice after initiating a claim for compensation for work performed while on active duty. The nature of the problem and the need for experience and expert knowledge remain the same. The same collective bargaining agreement must be construed with the same need for uniformity of interpretation and orderly adjustment of differences.

. The union could, pursuant to 45 U.S.C. § 184, attempt to convene a system board of adjustment where appellant’s minor dispute would be arbitrated. For a discussion of appellant’s argument *1052 that the union would not assist him in processing his grievance, see infra part IV.
. The airline and railroad industries differ in the procedures available tо their respective employees for arbitration of disputes. In the railroad industry, the failure of the employer or the union to convene a special board of adjustment is not fatal to a grievant's administrative claim; § 153 of the RLA creates a National Railroad Adjustment Board to which disputes can be taken.
See 45 U.S.C.
§
153,
par. First, (i)-(j) (1988);
Elgin, J. & E. Ry. v. Burley,
Whether airline employees also have a right to pursue claims individually is less clear.
See Stevens,
Unlike in the railroad industry, however, airline employees do not have a national board to which they can resort, for although a National Air Transport Adjustment Board was contemplated in 45 U.S.C. § 185, it was never сreated. If the language of § 184 is interpreted in the same manner as that of § 153, airline employees will have no way to pursue administrative claims without union assistance. Because Congress intended to extend to airline employees "the same benefits and obligations available and applicable in the railroad industry,”
