I just got an answer from us airways concerning the seat pitch on A333:

Thank you for visiting usairways.com.
Below is a listing of the seat dimensions and pitch on our aircraft.
Airbus 330(333)
Envoy Class: 60.0" 19.5" 36 Standard seats, electronic recline and
lumbar support
Envoy (Row 1) Class: 94.0" 19.5" 6 Flat bed seats
Coach Class: 31.0" 17.0" 224 seats, adjustable headrests and lumbar
support

Bulkhead seats may have slightly more leg room, but all of your personal
items must be stowed in the overhead bin during take off and landing.
Exit row also has more leg room, but both bulkhead seating and exit row
seating are given out on the day of departure at the airport.

so...seatguru is also wrong...
