In today's post COVID-19 era most all passenger airliner related industry is dead in the water for the short term anyways.
It will take another year or two to return depending on the per-longed period many of the budget airliner may not be afloat placing many of their planes into the used air frame market.
Many aviation control bodies may also change regulations to install ultra-violet lamps within the cabins to ensure sanitation of air borne virus and spacing between passengers to limit transmission within cabin which will be the last nail in the coffin for all budget airliners.
Although not directly related the wide spread use of tel-conferencing utilizing app such as Zoom and/or MS Teams will also have a significant effect in future passenger airliner related industry as well.
The two pillars of passenger air is tourism and corporate in which the majority for corporate is meetings/seminars.
Now that we have a way to facilitate meetings including breakout sessions with these apps. many organizers are going to re-evaluate how they are going to hold meetings since it is much more convenient and cheaper to do it online than to have people assemble to a certain location and hold those meetings cutting all travel expenses.
