There is nowhere to know if they will be using a Swoop plane. WESTJET owned Swoop. It was their low fare airline, but now they have discontinued Swoop and just using the planes for regular Westjet flights. They are very basic aircraft with no Wifi or entertainment and seats closer together and no premier seating. They say they are in the process of updating the Swoop planes which may take awhile. My flight numbers were changed as well, but I only realized it was a Swoop plane upon boarding.
