17 Profit Sharing

Understanding Delta’s Employee Profit Sharing Program • Eligible profit sharing pool is determined by Delta’s adjusted pre - tax profits ─ Employees receive 10% of first $2.5 billion of eligible profits and 20% above that ─ Delta incurs employer taxes and other costs which add 2% to 2.5% at 10% level and 3% to 4% at 20% level • Profit sharing accrual is updated monthly 18 Rewarding employees through profit sharing is a unifying force $0.5B $1.1B $1.5B $1.1B $1.1B 2013 2014 2015 2016 2017 Annual Profit Sharing

20 Refinery

Financial Statement Impact of the Refinery • The refinery provides ~200,000 barrels per day for the airline through production or exchange, approximately 80% of Delta’s domestic consumption ‒ Provides ~30% natural offset to rising jet crack spreads as the crack spread is the primary profit source for the refinery • Refinery segment profits are netted against the fuel purchase cost ‒ The impact of pricing arrangements between the airline and the refinery with respect to the refinery's inventory price risk hedges are reflected as airline segment fuel hedges 21 Refinery results reflected in fuel expense 3Q18 Press Release: N ote: Adjusted for special items

Financial Statement Impact of the Refinery (continued) • Roughly $ 300 - $500 million per year in products are sold to third parties at zero margin • Sales are recorded in other r evenue with a corresponding expense in ancillary business expense • Delta’s TRASM and adjusted margin figures exclude the impact of third - party refinery sales 22 Third - party sales are profit neutral; excluded from unit revenue 3Q18 Press Release: 80 49 11 95 61 67 129 245 213 216 108 ~30 1Q16 2Q16 3Q16 4Q16 1Q17 2Q17 3Q17 4Q17 1Q18 2Q18 3Q18 4Q18E Third - Party Refinery Sales ($M) N ote: Adjusted for special items

23 Ancillary Businesses & DGS Transaction

3Q18 ($M) (¢) Total Operating Expenses 10,311 14.15 Less: Aircraft Fuel (2,498) (3.43) Less: Ancillary Businesses and Refinery (410) (0.56) Less: Profit Sharing (395) (0.54) NF-CASM Expense Base 7,008 9.62 Capacity (ASMs) 72,875 NF-CASM excluding profit sharing 9.62¢ Delta's CASM-ex Calculation Impact of Delta’s Ancillary Businesses • Delta’s ancillary businesses include MRO, DAL Global Services (DGS), Delta Vacations , Delta Private Jets (DPJ ) and Delta Material Services (DMS) • Ancillary business are complementary to the airline operation, but have different seasonality and trends • Delta excludes expenses related to its ancillary businesses from CASM - ex fuel to allow for a clean comparison of the cost performance of the airline, as these costs are not directly impacted by capacity 24 Ancillary businesses are complementary to the airline and are earnings and cash flow positive

DAL Global Services Transaction Overview • DGS will be combined by year - end 2018 with a subsidiary of Argenbright Holdings to create a premier aviation and ground handling service provider − Delta will be an equity partner with a 49% stake in the combined company − Better positions DGS to grow aviation, security, and ground support equipment maintenance services Financial Impact: 2018: One - time gain in non - operating, finalized at transaction close 2019: Results from 49% equity interest stake to be recorded in operating expense as an offset to contracted services • Reduction in other revenue and ancillary expense • Minimal CASM impact due to shifting of certain expenses to contracted services 25

26 Taxes

Book Tax Rate Cash Tax Rate 10 - 12% 23 - 24% 27 Expect to be full cash taxpayer in 2020 Delta’s Cash Tax Rate is Below Book Tax Rate • Delta’s cash tax rate is significantly below its ~23 - 24% book tax rate due to: ─ Accelerated depreciation ─ Pension funding ─ Permanently reinvested foreign earnings • Under current tax law, Delta does not expect to be a full cash taxpayer until 2020 ─ Cash tax rate is expected to remain roughly 10 points below the book tax rate $8.3B $4.7B ~$2.5B 2016 2017 2018E Expected 2018 Book vs. Cash Tax Rate (Ex. N.O.L.’s) Net Operating Loss Carry Forwards

28 Airport Investments

• Delta approaches each construction project individually, working closely with airport partners • Airports have different structures for how they charge airlines fees and rents − Landing fees are assessed by landed weight and pay for airfield - related costs to construct, maintain, and operate runways and taxiways − R ents cover the cost to construct, maintain and operate landside assets ( primarily terminals and concourses), assessed by square feet leased or enplaned passengers Delta’s Airport Investments 29 LGA • • • • • • • • • • • • • • • • • • Delta maintains project control over cost and timeline • Cash or debt financing by Delta locks in ownership costs and avoids periodic rent increases • Provides greater control of customer service and operational disruption • Facility rents decline, depreciation increases (and interest expense, if financed) • Example: LGA Delta Managed / Financed • Delta maintains project control over cost and timeline • Costs paid up front or reimbursed by airport • Provides greater control of customer service and operational disruption • Airport issues bonds to fund construction • Airport recovers costs through rents/fees over lease term • Examples: ATL – Delta concourses, LAX Delta Managed / Airport Financed • Airport manages project and finances through bond offerings • Delta engages with airport to mitigate potential customer impact from construction • Delta has less input on costs, design • Airport recovers costs through rents/fees over lease term • Examples: ATL – Airfield, SLC, SEA Airport Managed / Financed Renovation funding of key airports including ATL, LAX, LGA, SEA, and SLC

Taking a Closer Look at the Financial Impact of LGA 30 Self - funded renovation of Delta’s LGA terminals drives greater certainty in long - term cost structure • Benefits to self - funding LGA: ‒ Lock in majority of long - term ownership cost, avoiding periodic rent increases ‒ Added control over product decisions, such as concessionaires and finishes, provides competitive advantage over common - use carriers ‒ Significant control over construction schedule • $3.3 billion funded by Delta, with $1.5 billion already on hand ‒ 2018 bond issuance matures between 2022 and 2036 with a blended average interest rate of 3.8% • ~$600 million funded by Port Authority • Project milestones: Concourse G opens late 2019, Concourse E and head house completed late 2021 • Pay same landing fees as Central Terminal occupants • Facilities rent declines, depreciation increases • Capitalized interest expense straight - lined over lease term • Interest expense increases as portions of the facility open Income Statement • Municipal bonds as debt, funds as long - term restricted cash • Long - term restricted cash decreases, lease hold improvements increase as ground assets are added • City leases assets to Port Authority; Delta subleases from Port Authority with a ground lease agreement through 2050 Balance Sheet
