A number of nations who have reduced their Corona burden to very low numbers or eliminated it are in talks about opening for mutual travel, and air “corridors” between them next month. My guess is that more nations who are currently in the process of easing out of lockdown as their infection rates fall will join them. A lot of flights will be back to normal towards the end of June. The exceptions will be the countries that cannot manage the virus. I don’t know what is going to happen there. Shut out from travel networks, long quarantines or strict testing procedures?
In recent years, first-class fares have generally been what, about 4x coach fares?
I’d be satisfied if they left middle seats unoccupied and required everyone to wear masks. That would require ticket prices to go up by a factor of 1.5x, not 4x.
Yes, I’d pay that.
Before the virus, I always sought out the cheapest airfare possible. As seat size became smaller, I wondered if they’d ever offer even cheaper fares for this willing to stand, knowing I’d go for it.
So how about individual plexiglass(?) tubes? The tube rotates around, creating an entry. You step in and rotate your tube closed.
I’d add that the mask requirement would have to have serious teeth to get me back on airplanes, as in, “you wear your mask properly except when actually putting stuff in your mouth, and if you give us problems about it, we land the plane at the nearest airport and escort you off.”
A few cases of people taking off their masks once airborne enroute to Orlando being dumped in Greensboro, or headed to L.A. and finding themselves in Omaha, would get the message across admirably. 
More than that, since the person behind you is not six feet away. And the person in front you you is even closer if they recline their seats.
That’s the one, and the one I was referring to. I saw the story on the local news.
I don’t believe for a moment that you know the first thing about travel.
Because they’re too close, I’d have to pay more??
Could you try again? I can’t parse this reply.
I think the demand for Business and First class seats will improve, with social distancing already baked into these classes. Service will probably suffer, with elaborate menus and personalized dining services replaced with standard tray-based meals and as limited contact as possible. It remains to be seen if Business and First fares will go up or down.
I’ve no doubt that in the short term we’ll see a mix of every conceivable pricing strategy as airlines desperately try to get some kind of dough rolling in. Higher fares? Lower fares? Unusual deals? They’ll try it all. Long term it’ll just be the same as it was before… but some major airlines might not exist anymore.
But if this were the case, then you would expect an airplane with a Covid passenger to see ***everyone *** aboard eventually come down with the illness. As I understand it, there have been plenty of flights in which a passenger was found to have Covid yet the others all failed to come down with the virus.
Delta Airlines claims that its HEPA filters can filter out even virus-sized particles; I’m not sure if that’s true or possible.
About that, what happens to customers holding tickets if an airline folds?
I don’t have any first hand experience, but I remember airlines like TWA and PanAm.
If you paid with a credit card, you file a dispute with the credit card company and they refund the cost of your ticket. Then the credit card company tries to get money from the airline in bankruptcy court. If you paid by some other method you might just be out of luck. If you bought trip insurance that might be an avenue you can take as well.
By the way one of the airlines you mentioned, TWA, didn’t just go out of business. They were acquired by American Airlines. So in that specific case AA probably had to honor TWA tickets.
