The type of aircraft is the same 737- 800. If you booked any of the economy seats, nothing will change even if they use a SWOOP plane. However those planes have no premier seating, all economy so if you booked the bigger seats, they do not exist. No wifi or entertainment either on the Swoop planes. Everything stayed the same for my flight with only the change in flight numbers. You will be fine, I'm sure.
