Politics aside, I can't imagine any sitting president facing an election year would let tens/hundreds of thousands of people lose their jobs right at the time when your political opponent is ready to strike with attack ads and make a push to take your job.
Furloughs for us will happen 4 weeks before a presidential election. Who knows who else will be in the same, or worse boat as the airline industry at that point. Millions are going to need more aid before this is over or even comes back in a 2nd wave. Red tie, blue tie or yellow tie, doesn't matter, I feel it would be political suicide to do nothing right before the general.
I don't think the airlines will see any more help since we already got billions, but other sectors certainly still need help, and more importantly, people need it as well.
