WestJet announced the airline's first flight from Alberta to Hawaii on its own Boeing 767-300 extended-range aircraft. To this point, flights to the Hawaiian Islands had been taking place on leased aircraft. WestJet took delivery of its first Boeing 767-300 on August 27, 2015 and has been flying the aircraft between Calgary and Toronto in order to obtain Extended-range Twin-engine Operation (ETOPS) certification.

This certification allows the aircraft to be operated for extended distances over water and is required for WestJet's service to Hawaii and to London Gatwick, which commences service in May 2016. WestJet's Boeing 767-300 service to Hawaii departs Edmonton on January 10 at 8:15 a.m. and arrives in Maui at 12:37 p.m. The airline will operate two 767-300 aircraft from Calgary and Edmonton to Honolulu and Maui. Each aircraft seats 262 guests.

The aircraft include a Plus cabin with 24 premium seats in a two-by-two configuration, hot meals and all of the other amenities associated with Plus. The main cabin has 238 seats, with two seats on either side of the aircraft and three in the middle. One of the 767s will be equipped with WestJet Connect, the airline's new inflight entertainment and wireless connectivity system while the other will include tablets loaded with movies and popular televisions shows.

By spring, both aircraft will be equipped with WestJet Connect. WestJet's seasonal service between Alberta and Hawaii began December 11, 2015, using two leased 767 aircraft from Omni Air International pending receipt of federal government certification for extended operation of WestJet's 767s, which was received on December 30, 2015.
