It only says B767-ER or 764)
The CO website posts no information, ever as far as I can tell, on which version of aircraft model is being flown.
Actually, the pda website will give you the plane number, from which you can use the OnePass FAQ to figure out which configuration it is. But this is not until only a few days before your flight.
