Sorry if I am late to this conversation, but why would there be open A320 slots for newhires? Is it due to a specfic base location? I thought all of the very junior E190 pilots wanted to bid the Airbus? What's with the vacancies on the Bus?
Outside looking in since I'm not employed there (fingers crossed, though), but it's possible they had Airbus FOs bid 190 CA, and the 190 FOs that bid CA couldn't hold it. The FOs leaving the bus for the 190 CA seats could leave 320 FO vacancies open. I could see a 190 FO, even junior, staying on the 190 rather than bidding over to the bus if they were gonna hold a line faster or didn't want to go to another base.
