I fully understand why the general public would think the same. However, be thankful that another extension will help save some folks from being on the street, regardless of the industry they are in. And-BTW- there are more than just the aviation industry included in these assistance packages. Let's just look at it as hundreds of thousands of Americans holding onto their jobs and not flooding the streets as well as unemployment numbers and cost as well.
This has NOTHING to do with UNION ENTITLEMENT! Yes the second push for further assistance was started by the unions at all airlines begging for an extension, But don't forget it was also the airlines, airports, and other industries pushing congress as well. This has nothing to do with only unionized jobs, it's all jobs rather union or not included within the job categories that "CONGRESS" decided to cover for a very important quicker and safer recovery of the economy when the time comes.
I still think AA and even maybe United will still maybe have to cut the overstaffed employees, so I am thinking they may not agree to the extension and not receive any more assistance so they can take the road of layoffs, rifs and furloughs WITHOUT having their hands tied. OR, they will still take the assistance and comply for the time period (March 2021) and then pull the trigger April 1st instead of on Oct 1 2020. In other words I don't see all airlines taking the 2nd round so their hands are not tied so they can do what they really want to do and downsize, and maybe even more than originally thought in order to bring their financials in line.
