How Delta, United, American, and Southwest Are Rebuilding Pilot Pensions Through Market-Based Cash Balance Plans

For most airline pilots, pensions are something we remember rather than something we expect.

During the bankruptcy era of the early 2000s, traditional defined benefit pension plans disappeared across much of the industry. United and Delta pensions were terminated and assumed by the Pension Benefit Guaranty Corporation (PBGC). American’s legacy pension was frozen, and Southwest remained a defined contribution airline. Today, retirement income for most pilots depends heavily on 401(k) plans and company retirement contributions.

But over the last several years, something significant has happened.

Delta, United, Southwest, and American have all negotiated Market-Based Cash Balance Plans (MBCBPs). While these plans are not traditional pensions, they represent the closest thing the airline industry has seen to a pension revival in decades.

The surprising part?

Each airline solved the retirement problem a little differently.

The Problem That Created the MBCBP

Pilot pay has increased dramatically across the industry.

As compensation rose, more pilots began running into IRS limits that restrict how much money can be placed into qualified retirement plans. The two most important limits are:

The 415(c) Annual Addition Limit

• Limits the amount that can be contributed annually to a qualified retirement plan.

The 401(a)(17) Compensation Limit

• Limits the amount of compensation that can be considered in calculating qualified retirement contributions.

For years, these limitations caused highly compensated pilots to lose part of the retirement benefit negotiated in their contracts. Airlines might promise an 18% retirement contribution, but IRS limits could prevent all of that money from reaching a qualified retirement account.

The solution was the Market-Based Cash Balance Plan.

What Is a Market-Based Cash Balance Plan?

Think of the MBCBP as a retirement overflow account.

When retirement contributions exceed what can fit inside the traditional 401(k) structure, those dollars can be redirected into a separate retirement vehicle instead of becoming immediately taxable income.

The result is:

• Additional tax-deferred retirement savings
• Continued employer retirement contributions
• Pension-like treatment
• Professional investment management

For pilots earning well into the six figures, the value can be enormous.

Delta: The Industry Leader

Delta was the first major airline to negotiate and implement a Market-Based Cash Balance Plan.

Delta’s structure is straightforward:

• 18% company retirement contribution beginning in 2026
• Excess contributions above both IRS limits flow into the MBCBP The key distinction is that Delta uses the MBCBP for:

In practical terms, Delta created a system that captures retirement dollars affected by either IRS limitation and keeps them inside a retirement structure rather than paying them as taxable compensation. For many pilots, this is why Delta’s MBCBP became the industry benchmark.

United: Maximum Flexibility

United pilots negotiated a Market-Based Cash Balance Plan as part of the 2023 pilot agreement. However, unlike the MBCBPs currently operating at Delta, American, and Southwest, United’s plan has not yet been fully implemented. As of this writing, the MBCBP exists in the contract, but pilots are still awaiting activation of the plan and final implementation details. Industry observers generally expect the plan to become operational in 2027, although pilots should rely on official communications from United and ALPA for updates.

What makes the United design particularly interesting is the flexibility built into the negotiated framework.

Rather than forcing all retirement overflow contributions into a single destination, the contract allows pilots to direct excess retirement dollars into either:

• The Market-Based Cash Balance Plan (MBCBP), or
• The Retiree Health Account (RHA VEBA)

Like Delta, United applies this treatment to both major IRS limitations:

If implemented as negotiated, United’s structure would provide pilots with retirement planning flexibility not currently available at the other major airlines. Some pilots may prefer the estate-planning and retirement accumulation benefits of the MBCBP, while others may value the tax-advantaged healthcare features of the RHA.

For now, however, the key point is that these provisions describe the negotiated framework contained in the contract, not a fully operational plan. Until implementation is complete, United pilots continue to operate under the existing retirement structure while awaiting activation of the MBCBP.

Southwest: A Different Approach

Southwest’s MBCBP is unique because it includes direct company contributions.

The Southwest agreement provides:

• 2% company contribution beginning in 2026
• 18% NEC in 2026

However, the SWAPA comparison revealed an important distinction.

Unlike Delta and American, Southwest’s original structure did not place all compensation-limit excesses directly into the MBCBP.

That doesn’t mean the plan is inferior. In fact, Southwest negotiated direct MBCBP contributions that the other airlines do not provide. But it does mean Southwest’s design differs from the Delta-style model that captures both IRS limits inside the cash balance plan.

American: Matching the Industry Standard

American’s 2023 agreement established a Market-Based Cash Balance Plan that closely resembles the Delta model. Like Delta, American uses the MBCBP to address both of the IRS restrictions that impact highly compensated pilots.

American’s contribution levels mirror Delta and United:

• 18% NEC in 2026

As a result, American joined Delta in creating a retirement structure that uses the MBCBP to address both major IRS retirement limitations.

The Real Story: Not All MBCBPs Are Equal

Airline pilots often talk about Market-Based Cash Balance Plans as though they’re identical.

They aren’t.

A better comparison looks like this:

That distinction may become increasingly important as pilot compensation continues to rise and more captains exceed IRS compensation thresholds.

The Bottom Line

For decades, airline pilots watched traditional pensions disappear.

Today’s Market-Based Cash Balance Plans are not the guaranteed pensions of the past, but they represent a significant step toward restoring retirement benefits that exceed the limitations of a traditional 401(k).

Delta built the model. American adopted a similar structure. United added flexibility through the RHA. Southwest created a unique hybrid approach with direct company MBCBP contributions.

The result is something few pilots would have imagined twenty years ago: all four major pilot groups have negotiated retirement structures specifically designed to preserve retirement dollars that would otherwise be lost to IRS limits.

That may not be a return to the pension era, but it is certainly the closest thing the airline industry has seen in a generation.
