I wouldn't expect any hiring for a while. There are still pilots on furlough and downgraded captains. And almost zero attrition.
The reason for the recalls has been the steady increase in flight hours assigned to AWAC by US Airways. This is a summer increase and it is not known if that will continue into the fall and next winter.
The last thing anyone wants is to recall pilots and then re-furlough some of them.
Hate to rain on anyone's parade, but that's reality. The fact that there have been some recalls and now some re-upgrades is good news. But it's very, very slow.
