Key Lime operates the metroliner single pilot. Ameriflight operates the B1900 single pilot. Beech 99 I believe is operated by Alpine Air single pilot. Key Lime doesn't participate in EJ as far as I know. If these companies required two pilot ops, there is no way eagle jet would be able to get visas for foreign pilots. The foreign pilots don't get work visas, they get another category visa. Captains get a paid bonus for taking an eaglejet P2F pilot along for the ride at Ameriflight.
