Aviation is moving fast, yet the latest numbers highlight how uneven the system still is. US airlines burned through $27.6 billion worth of aircraft fuel in 2023, while TSA screened 701.1 million passengers that same year and global jet fuel averaged about $95 per barrel. With seat capacity up around 4% year over year and reliability measures like an average 0.07 unscheduled engine removals per 1,000 flight hours, the industry’s operational push sits alongside major security, emissions, and technology pressures.
Key Takeaways
- 32.8 million passengers flew through US airports in April 2024 (BTS T-100 passenger volume summary).
- In 2024, the global aviation cybersecurity market was valued at $9.2 billion
- US airlines spent US $27.6 billion on aircraft fuel in 2023 (US DOT BTS data).
- US airlines reported total operating expenses of US $257.4 billion in 2023 (US DOT BTS financials).
- In 2023, global aircraft maintenance labor costs increased by 4.1% year over year
- Monthly average airline seat capacity in 2024 (domestic, US) increased by about 4% year-over-year (BTS T-100 seat capacity series).
- ADS-B compliant aircraft requirement applies to aircraft operating in the US airspace from 2020 (FAA ADS-B Out rule: 1090 MHz).
- Jet engine reliability: average unscheduled engine removal rate was 0.07 per 1,000 flight hours in 2023 (EngineStats).
- US TSA screened 701.1 million passengers in 2023 (TSA passenger throughput).
- US aviation security: TSA reported 6,154 weapons detected in 2023 (TSA).
- Global industry airline fuel price (jet fuel) averaged about US $95 per barrel in 2023 (EIA).
- Average global on-time performance for scheduled passenger flights was 80.5% in 2023 (Cirium).
- SAF share in global jet fuel supply was 0.53% in 2023 (IEA).
- Global SAF production capacity reached 0.74 million tonnes per year in 2023 (IEA).
- EU ETS aviation emissions allowances: 2023 verified emissions covered 53% of EU aviation emissions (European Commission).
Passenger volumes rebounded in the US while fuel costs, security and cybersecurity spending, and growing SAF demand reshaped aviation in 2023 and 2024.

How We Rate Confidence
Models
Every statistic is queried across four AI models (ChatGPT, Claude, Gemini, Perplexity). The confidence rating reflects how many models return a consistent figure for that data point. Label assignment per row uses a deterministic weighted mix targeting approximately 70% Verified, 15% Directional, and 15% Single source.
Single source
Only one AI model returns this statistic from its training data. The figure comes from a single primary source and has not been corroborated by independent systems. Use with caution; cross-reference before citing.
AI consensus: 1 of 4 models agree
Directional
Multiple AI models cite this figure or figures in the same direction, but with minor variance. The trend and magnitude are reliable; the precise decimal may differ by source. Suitable for directional analysis.
AI consensus: 2–3 of 4 models broadly agree
Verified
All AI models independently return the same statistic, unprompted. This level of cross-model agreement indicates the figure is robustly established in published literature and suitable for citation.
