Because
It's nothing personal against Sunny but the attempt to try and fly 10 800s all of sudden seems like a far reach. It sounds like Sunny is financially in trouble because of it's business model and this damn covid thingy. A number of sources have said that Sunny won't be able to handle the Amazon contract just because there are a lot of penalties associated with performance.
Again, nothing against Sunny or it's crews. Hell, maybe it's Sunny that buys MAI!
Good luck to everyone
