TTG at 70: Aviation's highs and lows through the ages

Meanwhile, in the US, a disrupter was about to shake up short-haul flying for ever. Southwest Airlines’ first flight from Dallas to San Antonio in 1971 was only an hour but with fares that made it cheaper than driving – a business model that has seen the carrier grow to become the fourth-biggest in the US today.

It was the model copied (with Southwest’s permission) by Ryanair, which began flying in 1985, and to a lesser extent easyJet, from 1995. Both of these airlines were helped by the EU’s open skies policy, which allowed carriers to fly anywhere in Europe, breaking the “two airline” norm which had held sway for decades.

The burgeoning number of no-frills carriers in the 1990s also dispensed with the industry’s “Saturday night rule”, which penalised travellers for not staying over a weekend, thereby lowering prices for business customers and winning an important client base from what became known as “legacy” carriers.

Another significant regulatory milestone came in 2008 when an EU and US deal removed some illogical restrictions on air travel. An example of this was a ban on Delta Air Lines serving Atlanta from Heathrow, meaning Delta could not connect its own hub – the world’s busiest airport – to Heathrow, then the world’s busiest international airport.

The deal subsequently opened the door for Norwegian Air and its successor, Norse Atlantic Airways, to offer no- frills transatlantic flights from the UK. To the industry’s relief, the agreement remained in place following Brexit.

Norse and Norwegian were assisted in their ambitions by new aircraft developments. Both used the Boeing 787, introduced in 2011, to operate their transatlantic schedules, with its revolutionary composite structure making it lighter and therefore more fuel-efficient. It and Airbus’s answer, the A350, now enable Qantas to fly non-stop from the UK to Australia.

In terms of aviation’s geography, developments in the Middle East cannot be ignored. Emirates first flew in 1985 when Dubai was best-known as a refuelling stop for flights to Asia. Emirates’ growth has fundamentally changed global flying patterns, with Dubai now the world’s busiest international airport.

Via hub development and persuading passengers that one-stop long-haul is acceptable, Dubai, Qatar, Abu Dhabi and latterly, with its new Istanbul airport, Turkey, have skewed travel patterns and advanced whole regions.

However, for all its advances, the airline industry has taken one step backward. In 2003, TTG reported from onboard Concorde when it was withdrawn from service. It ended an era of supersonic flight that meant London to New York took just three-and-a-half hours, providing you could afford the equivalent of £11,372 in today’s money for a return ticket – and too few could.

Concorde cruised at 1,350mph, twice the speed of sound, and left the skies exactly 100 years after the Wright brothers’ first flight made it all possible. Concorde was perhaps the ultimate gas guzzler and was also extremely noisy. A possible successor was declared in 2021 by US firm Overture, with its Boom aircraft, which has pledged to use sustainable aviation fuel (SAF) to answer criticism of its environmental credentials.

What did it all mean?

In 2023, SAF is now the buzzword as airlines face an almighty challenge to achieve net zero by 2050. The next few decades will be critical for an industry that, in little more than 100 years, has allowed ordinary people to travel the world.

For all its achievements, aviation’s next big quest – sustainability – must still be overcome.
