I have a group friends (from the USA) who left and are on the 767 at ANA/JP Express (I think they are one contract now).

They seem to like it.

History of them:
Skywest CRJ Capt, went to ANA pax side as a 737 capt. Did it for X years, then went to 767 Capt where you fly both pax and cargo

Furloughed AA FO:
Went to ANA 767 FO, freight side. Upgraded to CA and now flies both pax and freight, as they are "one" operation now.

Skywest CRJ Capt:
Same as above AA FO, Went to ANA 767 FO, freight side. Upgraded to CA and now flies both pax and freight, as they are "one" operation now. Got sick of "it" and came back to the USA as a Virgin American FO. He saved a LOT of money while working for ANA though....

Furloughed ATA 757 Capt:
Went to NCA Cargo (diff company) as a 747-400 FO. Upgraded to 747-400 Capt after XX years. Still there. Thought about quitting for FedEx while he was still an FO at NCA. Now that he is a capt, I dont think he'd quit for anywhere.

Seems ANA and NCA are good contract gigs.
