With little help from Flightradar24, it seems to be A330-202 9H-TQP that is flying for Air Transat. And if HiFly's website lists details right (although there they still use CS-TQP as id, they must have switched the registration country at some point), there are 31 business and 267 economy class seats, making 298 total. Seat pitch 46"/47" in business and 31"/32" economy and Panasonic 2000 video entertainment system.
