The BBC documentary, Cheap Flights: What They Really Mean for You, sheds light on the far-reaching implications of budget air travel, exploring the environmental, societal, and financial impacts of our growing love for affordable flights. The program, available now on BBC iPlayer, challenges viewers to reflect on the true cost of flying and whether sustainability goals can be achieved without significant trade-offs.
Since the 1990s, the rise of budget airlines like Ryanair, EasyJet, and Wizz Air has made international travel more accessible to millions. What was once a luxury is now routine for holidaymakers, with over 200 million passengers flying in and out of the UK annually. This democratization of air travel has fostered global connections and economic growth, but at a high environmental cost.
“Cheap flights have transformed the holiday industry,” notes Professor Gordon Liu, a marketing strategy expert and consultant for the program. “However, this convenience comes with significant trade-offs, particularly in terms of carbon emissions and climate impact.”

Enter NowAviation accounts for 2–5% of global CO₂ emissions, with non-CO₂ emissions amplifying the industry’s warming effect. Cheap Flights critiques the UK’s “Jet Zero” strategy, which aims for net-zero emissions in aviation by 2050, arguing that it underestimates the environmental impact of exhaust emissions.
Professor Sir Dieter Helm of Oxford University provides a sobering perspective:
“Aviation is too cheap because you’re not paying for the pollution, the surface infrastructure, or the environmental damage caused by airports. Polluters have to pay, and the polluter is the passenger.”
Offset schemes are another focal point of criticism. While planting trees to offset emissions may sound effective, the program reveals that offsetting the annual emissions of aviation by 2050 would require 1.9 billion trees—an area nearly the size of Wales.
The program explores emerging solutions such as Sustainable Aviation Fuel (SAF), battery-powered planes, and hydrogen technology. SAF, touted as a cornerstone of aviation’s decarbonization, could account for up to 65% of the emissions reductions needed by 2050. However, experts like Helm are skeptical about its scalability, citing concerns about biofuel sourcing and availability.
Viewers also get a behind-the-scenes look at Gatwick Airport’s sustainability initiatives and the Humberside refinery’s efforts to develop alternative fuels. While promising, these innovations come with high costs, likely to be passed on to consumers. Duncan McCourt of Sustainable Aviation acknowledges this:
“Fares will increase by a few pounds, but much of the cost will inevitably fall on the consumer.”
With decarbonization efforts raising ticket prices, the program concludes that consumers must weigh their travel habits against environmental responsibilities. Presenter Michelle Ackerley investigates how travelers can make greener choices on a budget, while science reporter Fran Scott examines whether next-generation aircraft engines can deliver significant efficiency gains.
The documentary leaves viewers with an urgent question: Can the aviation industry truly revolutionize its operations to meet net-zero targets, or will cheap flights become a relic of the past?
