Hey B767. To answer your first question, I think AC is getting rid of their 747-400's because they only operate three of and they are moving towards a more standardized, common fleet. Also, the -400s are combi versions with only 260 seats so the A330 will be more efficient and offer similar capacity. Question 2: no, the A319's were never seen in the old AC colours. Deliveries of those began in 1996 and the new colours were introduced in 1992. And, no, I dont believe there are any old colour planes left. As for your last question, I can't help you there. Hope I've helped you out.
