Seems like a lot of guys are going the Envoy route to get their FW time sorted out. I'm not a mathematician but it seems like shelling out $12K to get 100 FW hours is chump change compared to getting in the door at a major a few years sooner. Especially considering the flow through to American is something like 6 years from Envoy. I may be wrong but I'm under the impression that American and United are both accepting plopter time provided you have your ATP. I feel like I'm missing key details.
Also, I don't want to sound like I'm bragging, but I just did the CTP in the airbus sim and I thought it was very similar to the Osprey - nothing cosmic at all. Different, sure, but not insurmountable. Even the dreaded V1 cut and single engine approach wasn't a big deal.
