Transport accounts for 42 percent of global CO2 emissions. Flight delays exceed 15 minutes on 8.5 percent of services under the current global benchmark. Statistics on emissions trends, operational performance, fuel costs, and passenger behavior outline the present state of the airlines industry.
Key Takeaways
- 42% of the world’s CO2 emissions come from transport across the globe (including aviation), per IPCC AR6 transport sector assessment
- $240 billion expected value of sustainable aviation fuel (SAF) investment globally by 2050 (scenario analysis) reported by industry research from BloombergNEF
- 31.3% of global aviation GHG emissions are from international aviation in 2019 (best estimate) per IPCC AR6 aviation chapter
- 8.5% of flights are delayed by more than 15 minutes on average in 2023 in the global benchmark used by Cirium’s on-time performance report
- 8.5% of flights delayed by more than 15 minutes on average in 2023 (global on-time performance benchmark used by Cirium).
- 7.2% year-over-year reduction in jet fuel prices (regional average) in 2023-to-2024 transition, as reported in EIA aviation fuel market updates
- 20.6% of airlines’ workforce is in ground handling roles in the US (share of aviation ground support employment), based on BLS Occupational Employment Statistics aggregation for NAICS 481
- $0.70 per liter average jet fuel price level in 2023 (global jet fuel price average reported by a reputable market data provider in annual review).
- 1,000+ airports in the US participate in FAA’s Airport Improvement Program (AIP) eligible airport list for capital grants; FAA publishes this participation through grant program guidance
- 2,700+ aircraft grounded during peak COVID period in 2020 (global airline fleet grounding), per FlightGlobal analysis using Cirium/Flightradar-type fleet data
- 7.4% of airlines’ fleet delivered in 2023 were next-generation fuel-efficient aircraft (A320neo/B737 MAX/A220 and similar) as per Cirium Fleet data summary
- 10.2% of global airline passengers used mobile boarding passes in a 2023 airline app usage study by Amadeus
- 24.0% of surveyed airlines planned to increase spending on airline digital merchandising and retailing in 2024, according to Amadeus travel payments research
- USD 78.2 billion total global airline passenger revenue expected in 2023 for US airlines (domestic + international passenger services), based on BTS economic statistics (Table 1.1)
- 0.08 aviation hull-loss accident rate per million flights in 2022 (Boeing Statistical Summary of Commercial Aviation Accidents).
Aviation faces climate and reliability challenges, yet SAF demand and digital payments are rising fast.
