They’re requiring masks, taking temperatures and speeding check-ins. But as one travel expert put it, “So much is uncertain right now.”

Airlines and airports around the world are doing everything they can to instill confidence that it is safe to fly again, despite the coronavirus pandemic.

But none of it is consistent. And it’s unclear whether the measures are enough.

Airports are also dealing with quarantine policies, established by local and national governments, that can be inconsistent or mishandled. When Americans returned from overseas in March, they often faced hourslong waits, with no social distancing, in airport customs lines, as well as conflicting or no guidance on quarantining.

This article by Tara Parker-PopeJune 9, 2020 for the New York Times explains 5 common sense rules to consider for everyday living as well as travel.  These may seem obvious for most of us but everyone isn't playing by the came rules or with the same concerns

1. Check the health of your state and community
2. Limit the number of your close contacts
3. Manage your exposure budget
4. Keep higher risk activities as short as possible
5. Keep taking pandemic precautions

These may seem obvious for most of us but everyone isn't playing by the came rules or with the same concerns

"In 2001, air travel was dealt a massive blow by the 11 September attacks, and the effects lasted years. But this was a ripple compared to what Covid-19 will do."

"Airbus chief executive, Guillaume Faury, has called the Covid-19 pandemic, “the gravest crisis the aerospace industry has ever known”. Similar sentiments have been expressed by the International Air Transport Association. The trade group – which represents nearly 300 airlines – says the industry is “only at the very beginning of a long and difficult recovery” and there remains “tremendous uncertainty about what impact a resurgence of new Covid-19 cases in key markets could have”.
Put simply, the industry will recover, but when that happens air travel is likely to look very unfamiliar."

Doctors warn that releasing a vaccine prematurely can do more harm than good.

Under normal circumstances, this process takes years. But these are not normal times, so the testing of potential Covid-19 vaccines is being collapsed into months, which could increase the risk of foul-ups. However, Dr. Francis Collins, director of the National Institutes of Health, gave his word that, despite being in a hurry to get an effective vaccine to the public, “we will not compromise on safety.”
Here’s how Dr. Offit, who is involved in supervising the Covid vaccine trials, described the necessary sequence of events:
A prospective vaccine is first tested on laboratory animals that normally develop Covid-19 when infected with the virus, such as mice, to see if it prevents the disease. This is called “proof of concept” that the vaccine can work. It is followed by Phase I and Phase II trials in perhaps hundreds or thousands of human volunteers. Researchers look for evidence that the vaccine is safe, and test different vaccine doses to find one that best results in antibodies that could protect against the virus. At least two vaccine candidates are already in this stage.
Now comes the big test, Phase III, a prospective placebo-controlled trial of tens of thousands of individuals to assess both safety and effectiveness. For one or more of the five promising Covid vaccine candidates being fast-tracked, this stage is expected to start in July. Each Phase III trial will entail 20,000 people who get the experimental vaccine and a control (placebo) group of 10,000 unvaccinated people. The trials will take place in areas here and abroad that are already, or expected to be, “hot spots” for Covid infections.
But depending on how prevalent the virus is this summer where the trials take place, it could take months — or even a year — to determine how well the vaccine prevents disease.
“That’s the only way to know if the immune response seen in earlier trials is protective in the real world,” Dr. Offit said. “If there’s little disease over the summer, it could be a problem. We may have to keep recruiting participants until enough people in the placebo group got sick to have a meaningful comparison with the vaccinated group. We can’t short-circuit the process.”

"With help from economists, politicians and business executives, I have tried to imagine what a post-Covid economy may look like. One message I heard is that the course of the virus itself will play the biggest role in the medium term. If scientific breakthroughs come quickly and the virus is largely defeated this year, there may not be many permanent changes to everyday life.

On the other hand, if a vaccine remains out of reach for years, the long-term changes could be truly profound. Any industry that depends on close human contact would be at risk."
