Commentary: Want to travel again? It’s not sitting in a plane you should worry about

To be able to travel again requires everyone’s combined effort – governments, airlines and passengers, says IATA’s Conrad Clifford.

SINGAPORE: To soak in the sights, sounds and scents of distant lands. To close business deals. To be with family and loved ones during special moments. Or to be at the bedside as a last breath is taken.

These are but some of the many reasons why we have taken a flight at some point in our lives. But it has not been possible to do so in the last six months ever since governments closed their borders to prevent the spread of COVID-19.

We don’t know when COVID-19 will be eradicated. The development of an effective and globally recognised vaccine is an important step. But it will take time for it to be produced and distributed around the globe.

Until that happens, we need to live with COVID-19 while taking precautions. This applies to reopening borders and restoring aviation connectivity around the world. 

Doing so will help with economic recovery and preserve the 65.5 million jobs globally that depend on the aviation industry.

Even though some countries have since reopened their borders, albeit cautiously, many people are still not travelling.

The fact is quarantine discourages travel. In a recent 11-market survey of travellers, 83 per cent indicated that they will not travel if there is a chance of being quarantined at their destination.

We recognise governments have imposed quarantine measures to prevent the importation of COVID-19 into their countries. Even if borders reopen, maintaining a 14-day quarantine has the same net effect of closing borders.

If the travel and tourism sector is to recover from the COVID-19 outbreak, an alternative to quarantine is needed.

That is why IATA has called for the systematic testing of all international travellers before departure. Pre-departure testing will reduce the risk of importing COVID-19 and be an alternative to quarantine. 

It can also reassure travellers that their fellow passengers on the same flight are not infected.

Travellers say they are willing to accept testing. In the same survey, 84 per cent of agreed that testing should be required of all travellers, and 88 per cent agreed that they are willing to undergo testing as part of the travel process.

We did not come to this decision lightly. The integration of systematic testing in the travel process will present logistical challenges and impact how people travel. 

We will need testing manufacturers to develop tests that can be deployed that are fast, accurate, scalable, affordable, and easy to use.

And considering the potential scale of testing required, non-medical personnel will need to be able to operate it effectively. Governments and health authorities will also need to agree on common standards so that tests administered in the departure country are accepted on arrival.

Much still needs to be done to achieve 100 per cent testing of all travellers prior to departure. We are working through the International Civil Aviation Organization (ICAO), which is leading efforts to develop and implement global standards for the safe operation of international air services amid the COVID-19 pandemic.  

We recognise that air transport is not the only sector with a critical need for testing. The needs of medical personnel must be the first priority. We hope testing for air travel will be made a priority after medical needs have been met.

Singapore’s Transport Minister Ong Ye Kung told Parliament on Oct 6 that Singapore is planning to establish air travel bubbles and replace the 14-day quarantine with COVID-19 testing. These are positive steps and will help the recovery of the aviation sector.

Aviation has a track record of pulling together to meet major challenges. We did it with security after 9/11, on the environment and on safety. 

It is a matter of time we will deliver an effective alternative to quarantine that will be accepted by governments and their health authorities.


I have spent almost 40 years in the airline industry, and a question I am often asked is whether it is safe to fly.

More than a billion people have travelled since the beginning of the year, with 44 cases reported where secondary transmission on board the flight potentially occurred.

That’s one case for every 27 million travellers. We recognize this may be an underestimate, but even if 90 per cent of the cases were unreported, it would be one case for every 2.7 million travellers.

The data is telling us that the risk of onboard transmission is low when compared to other public indoor environments.

There are reasons why the risk is low. There are factors in the cabin that naturally limit the spread of droplets – everyone faces forward, the seat backs act as a barrier between rows, people generally don’t move around very much on a flight, and the air in the aircraft cabin circulates from the top to the bottom of the cabin (instead of along the length of the fuselage).

The quality of the air on board is also much better than most indoor environments. Cabin air in modern aircraft is 50 per cent fresh air from outside the aircraft and 50 per cent recirculated air, which goes through High Efficiency Particulate Air (HEPA) filters that are 99.993 per cent effective in removing bacteria and viruses such as COVID-19.

The HEPA filters are of similar performance to those used in a hospital operating theatre or industrial clean room. And the air in the cabin is refreshed 20 to 30 times an hour, about 10 times more than most office buildings.

Besides the cabin characteristics, the industry has also taken steps to further lower the risk of transmission.


Safety is the aviation industry’s number one priority. That includes bio-safety. Following the COVID-19 outbreak, airlines have made changes to the travel experience to keep their passengers and crew safe.

If you board a flight today, you will be required to wear a face mask throughout the flight. Even the crew are doing so.

Masks are an important line of defence as they can, when worn properly, reduce the spread of COVID-19. This protects others on the flight in the event a person is infected and asymptomatic.

The inflight service has also been simplified. This is to reduce interaction between passengers and the crew. Congregation of passengers in the cabin is also reduced, for example, no queues to use the washrooms.

To minimise the risk of virus transmission through contact, airlines are performing deeper and more frequent cleaning to sanitise common areas. Common touch items, such as inflight magazines, have also been removed from the seat pockets.

These measures are part of ICAO’s take-off guidelines to restart aviation, which provides guidance for the entire travel process including the departure and arrival airports.


Passengers too have a role to play to prevent the transmission and importation of COVID-19, and protect themselves and their fellow travellers. Besides wearing a face mask properly throughout the entire travel process, it is important to practice good hand hygiene.

That means washing your hands regularly with soap or an alcohol-based hand sanitiser. Avoid touching your eyes, nose or mouth, especially after contact with commonly touched surfaces on the aircraft.

Given the characteristics of the aircraft cabin, the implementation of the take-off guidance across the industry, and precautions taken by passengers, we will be able to fly safely despite COVID-19.  

And when COVID-19 testing prior to departure is implemented, it will give passengers even greater assurance.

This crisis has demonstrated how much is lost when the world cannot travel. Some have said that travel is forever changed or reduced. I don’t think so.

For sure, business travellers will question their travel habits. And leisure travel will be impacted by economic uncertainty.

Although we are connecting through Zoom, Teams, Skype or other technologies, it is not the same as being there in person - to hug a loved one, to experience a new culture, or even to assess the body language of a potential client or partner when negotiating a business deal.

That is not something people forget or lose their desire for. We will see measures that mean people can fly again, and not restricted to essential flights only, and when we do so, you can be assured that it will be done safely.
