Podcast Summary: Business Daily – "Should we expect more airline delays?"

Host: Russell Padmore (BBC World Service)
Date: October 7, 2025
Main Theme:
This episode explores the growing unreliability of airline operations, focusing on how outdated and failing technology, staff shortages, cyberattacks, and organizational failures lead to delays and cancellations. The episode gathers insights from airport chiefs, software experts, pilots, and industry consultants to uncover the causes and propose solutions for the ongoing disruptions in global aviation.

1. Growing Disruptions in Air Travel

Key Points:

• Increasing passenger numbers coincide with more frequent technical disruptions at airports.
• Failures in check-in, boarding, and security systems are forcing airlines to delay or cancel flights.
• Frequent reports of significant delays due to a combination of local technical glitches, cyberattacks, and staff shortages.

Memorable Quote:

“More people than ever are flying, but airline business travelers or passengers taking a holiday are experiencing more disruption because technology used by aviation keeps failing.”
— Russell Padmore (01:01)

2. Causes of Aviation IT Failures

Outdated and Overburdened Technology

Brian Glick (Editor-in-Chief, Computer Weekly) [05:20-06:50]:

• Many airports still use software designed 10-20 years ago.
• Complex networks of interconnected systems make updating and maintenance difficult.
• Crashes often result from failed software updates or changes that can't be quickly reversed.

Quote:

“Some of these airports may be using software that was first developed 10, 20 years ago... There’s a huge amount of information that’s being shared and transferred around... all connecting into this extremely complex IT infrastructure.” — Brian Glick (05:20)

Reluctance to Modernize

• Cost and risk associated with replacing legacy systems discourage quick upgrades.
• High stakes make operators cautious about introducing major changes.

Quote:

“If the risk of replacing an older system that generally still works is greater than the risk and the cost involved in building an entirely new system, they're going to stick with what they've got.”
— Brian Glick (06:32)

3. The Ripple Effects of Delays

Knock-On Impacts

• System failures don't just affect one flight but can create a chain reaction, moving planes out of position and causing multi-flight disruptions.
• Costs mount for airlines due to compensation and the need to rebook or reposition aircraft.

Quote:

“It’s not just that one flight, it’s the knock on effect... The cost of that to airlines is huge. We need to stop this from happening because airlines will go bust eventually.”
— Jennifer Bradnam, Travel Counsellor (04:43)

4. The Passenger and Employee Experience

At Dublin Airport [08:01-09:29]:

• Passengers express growing resignation and frustration toward inevitable delays.
• Business travelers note the increasing need to allocate extra time for travel and the regular loss of connecting flights.

Quote:

“Absolutely. You know, between weather and technology, delays are more and more prevalent. And when you do travel you've got to allot extra time and just be patient.”
— Dublin Airport Passenger (08:57)

5. Airport Management Perspective: Resilience & Investment

Kenny Jacobs (CEO, DAA – Dublin and Cork Airports) [09:39-12:49]:

• Predicts increasing IT disruptions worldwide, from both cyber and infrastructure faults.
• Airports must test systems regularly (six times a year at Dublin) and build in redundancy – including multiple electricity sources and manual check-in options.
• The global nature of aviation means disruptions often have cross-airport impacts.

Quote:

“Every airport I think around the world will see more and more of this occurring... I think every airport needs to be more paranoid about this kind of occurrence in a healthy way so that you can build in proper resilience and be ready for it. Because ultimately how you respond is what matters most.”
— Kenny Jacobs (09:56)

On Modernization and AI

• Dublin Airport invests in modern systems and regularly tests innovations like AI in baggage screening.
• Advocates for robust, updated systems with built-in redundancy as a partial solution.

Quote:

“We are testing the use of AI in screening bags just to see how does it learn and how efficient it is... I think you will see AI, look at the weather, look at passengers... to make our jobs easier.”
— Kenny Jacobs (12:57)

6. Air Traffic Control: Systemic and Staffing Problems

UK and US Air Traffic Control Issues

• Case study: UK’s NATS suffered a $135 million loss due to a software glitch, worsened by remote work practices and faulty backup systems.
• In the US, chronic staff shortages and outdated federal systems have led to a reduction in flights and severe delays, especially at key hubs (e.g., Newark, Florida).

Quotes:

“The FAA is about 30% short staffed. So it happens around the country. What it does is it slows the air traffic down.”
— Scott Kirby (United Airlines CEO) (14:33)

“Well, we have here in the US we have an air traffic control system run by, staffed by, managed by the US Federal government that has not really kept it up. I mean, we just don't have enough people working there. It's been mismanaged.”
— Michael Boyd (Boyd Group) (14:54)

7. The Pilot’s View: Crew and Operational Challenges

Barry Eustace (Consultant & former Virgin Atlantic Captain) [16:33-18:08]:

• Flight crews are challenged by delays, constantly recalculating crew hours and fuel needs.
• Gate closures are usually enforced if passengers cannot make it due to delays; rarely are large numbers stranded from a single software incident, but broad malfunctions can impact many.
• Delays create cumulative disruptions due to the interconnected nature of airline operations.

Quote:

“The knock on effect... can be significant. And of course, you're dealing with a global four-dimensional chessboard here.”
— Barry Eustace (17:38)

What’s Needed?

• Investment in both personnel and the technical systems they rely upon.
• Proper leadership and steady financing are critical to maintaining flight safety and efficiency.

Quote:

“I think the answer is that you have to invest in both personnel and the equipment that supports them. You can't underfund critical flight safety and efficient leadership and management of a system is critical.”
— Barry Eustace (18:08)

8. Industry Economics and Future Outlook

• Aviation is a low-margin global business: in the past year, industry revenues were $36 billion, but profits were below 4% (21:44).
• Ongoing disruptions threaten both profitability and the vital connectivity air travel provides.
• The episode concludes with a call for investment in reliable, modern tech for the sake of both profits and passenger safety.

Key Time-stamped Takeaways

• 01:01 – Growing frequency of tech failures at airports
• 05:20 – Why legacy systems persist in aviation
• 06:50 – Best practices and response planning are crucial (Brian Glick)
• 09:56 – “Every airport... will see more and more of this occurring.” (Kenny Jacobs)
• 14:33 – FAA staff shortages slow US air travel (Scott Kirby)
• 17:38 – Pilots face a “global four-dimensional chessboard” of knock-on delays (Barry Eustace)
• 18:08 – Investing in both staff and tech is critical for safe and efficient operations

Conclusion

The mounting frequency of aviation delays stems primarily from aging infrastructure, insufficient IT investment, staff shortages, and rising cyber threats. While some airports, like Dublin, are prioritizing systemic resilience and technological upgrades—including experiments with AI—much of the world lags behind. Lasting solutions include modernizing IT systems, introducing redundancy, improving staff training and numbers, and embracing proactive crisis management. As the global demand for travel rises, the industry’s ability to modernize and manage increasing complexity will determine whether the skies become more—or less—travel-friendly in the years ahead.
