main entity: Which airline has a newer fleet in 2026?
  type: Question
  accepted answer: Answer
    text: Both United and Delta maintain identical 15-year average fleet ages, but Delta is modernizing faster with active Airbus A350 widebody deployment and established A321neo fleets. United is just beginning A321neo deliveries after 20+ years without new Airbus aircraft, indicating Delta's fleet is effectively newer despite the same average age statistic.
    language: en-US
main entity: Does United or Delta operate more flights?
  type: Question
  accepted answer: Answer
    text: United operates 982 mainline aircraft (58 more than Delta's 924), which provides greater capacity for high-frequency domestic service. However, American Airlines operates the most total flights among major US carriers at 2.2 million departures annually. Delta prioritizes premium long-haul routes over pure flight frequency.

  type: Question
  accepted answer: Answer
    text: Delta Air Lines is better for international travel due to its A350 widebody fleet expansion and premium-focused revenue strategy. These newer aircraft offer superior comfort for long-haul routes. United is expanding long-haul capacity but maintains a more domestic-focused strategy with less modern widebody deployment.
    language: en-US
main entity: Are there differences in aircraft reliability between the two airlines?
  type: Question
  accepted answer: Answer
    text: Delta's newer A350 and established A321neo fleets are more modern and fuel-efficient. United still operates significant numbers of aging A319/A320 aircraft, though Boeing 737-800/900ER aircraft in both fleets are generally reliable. Delta's newer widebody fleet likely has lower maintenance costs per flight hour.
    language: en-US
main entity: Which airline is more financially stable for 2026?
  type: Question
  accepted answer: Answer
    text: Delta demonstrates stronger financial positioning through diversified revenue streams including MRO services, cargo operations, and loyalty programs—beyond ticket sales alone. United's strategy is more ticket-dependent with primary focus on frequency and volume. Delta's Q4 2025 earnings showed successful premium revenue expansion.
