The timing on the 175 delivery has been well advertised and those have historically been pretty accurate. Most indications are little to no total fleet growth and we are slated to get more 175s than we have CRJs. Envoy (I think all levels from reserve FOs to training dept to MGT) would like to see them gone ASAP. A small and dying fleet helps no one except a few guys that want to retire without changing airframes.
