The last AE bid didn't result in many pilots bidding the ER. In fact more guys bid out of it than into it. That is why they had to put new hires there.
I don't expect to see many pilots bid to the ER until the International pay improves. $3 per hour and a few cents extra per diem doesn't make the ER very attractive. The strong Euro vs the weak Dollar make it a money losing proposition.
For pilots who want to live in NY it's a great option, but commuting to JFK even as a lineholder is a headache. I would expect to see pilots bid the 777 in NYC because of the pay, but the ER isn't worth it until the situation at JFK gets worked out.
For most it's better to bid a domestic 757/767 out of ATL. Lots of new hires on that airframe as well, so pre 07 hires should have a chance at a line there as well. Especially when the new hires in NYC bid back to domestic in ATL.
