While it’s true most US ‘Legacies’ have declared Ch.11 bankruptcy at some point, most were able to rebuild successfully back to profitability pre-covid. The unionisation of pilots and flight attendants has lead to the improvement and preservation of conditions (albeit losing pension programs which have been replaced by generous superannuation packages).
At the same time conditions at international ‘legacy’ outfits around the world have deteriorated. I’d be willing to go out on a limb and say that total compensation and conditions at US legacy airlines are way ahead of any airline gig around the world.
