Same here.
In 2011, my parents were meant fly on LY324 on a 763. And at roughly the same time, a Sun d'or was scheduled on the same route. But the Sun d'or had to go tech, and all the passengers (LY and Sun d'Or) were put on the same 744. And guess what? This 744 was the mighty ELH and it was its 1st week of operation with LY lol
