Welcome onboard

Your flights are operated by a Boeing 767-300/ER (winglets). It's normally a former first Choice aircraft, however it's a little early to confirm it. We'll know from May. The main differences between the premium cabins are detailed on our What Aircraft? guide. It's the number of seats / rows and the seat pitch that differs mainly, and slight variation to the seat design but the facilities are the same. IFE for your flight won't be released until May, and it'll change again beginning July for your return flight. Again, it's too early to confirm where the flight operates prior to your outbound flight. However it's probably TOM062/3 (La Romana, Dominican Republic).
