Air Contractors
prefer applicants to have 500hrs on type, but they can't always find them - I should know! Recent starters are a mix of experienced and newly type-rated FOs. (The reason toilets have been removed is that they couldn't be reached anyway once the aircraft is fully loaded with [bulk] freight... Most sectors aren't too long anyway, and the turnarounds
are longer - so we manage).
ATRs might be
supplemented at some point by 737s on the busier routes, not replaced altogether (not very cost-effective to carry 4-7 tons of cargo on a 737!)
Otherwise the above post is spot on.
Come to think of it, you can also try Dutch Antilles Express (DAE)
http://www.flydae.com, Interstate Airlines
http://www.interstateairlines.com , Solenta Aviation
http://www.solenta.com - and check
http://www.aviationjobsearch.com for an ad requiring ATR FOs in Russia (probably UTAir) on a 6-month contract. Avanti Air
http://www.avantiair.com have also been known to hire freshly type-rated FOs.
