MapleJet's first A320, delivered in 1989, shown here in 2002 following the airlines dissolution.
The A320 (and A319 and 321) were the replacement for the Boeing 737 and 727 fleet, ending a nearly 30 year reign by the Boeing company as the narrowbody fleet provider. This marked a shift away from Boeing in long haul orders as well, with the A340 replacing MapleJet's 747SP fleet. However, Boeing would retain a significant order with the 757 and 767 replacing MapleJet's DC-10 fleet on trans-Atlantic and some domestic routes.
The A340 would enter service in 1999, making it the last aircraft to be acquired before the original MapleJet went under in 2002.
