Actually due to rising costs of jet aircraft, USAirways will be bringing back 30 Shorts 360 aircraft from retirement. This due to the fact that USAirways refuses to pay market-rate for Boeing 757 leases.
And due to weight restrictions & center of gravity, the aircraft will only be fitted with 2 Envoy seats and 30 coach seats with a "generous" 31 inch seat pitch for use on our new trans-atlantic flying (ok, well it will almost make it trans-atlantic... err maybe they'll make it to Maine from Philly)
