well, first of all: happy bday emily! 

secondly: no clue what kind of fleet planning that should be 

[Zobelle]

Happy birthday.

Happy birthday! and having 15 different aircraft types by the "end" might be a little tricky

Happy birthday, but what the actual hell? The numbers are completely arbitrary and don't make any sense of course, and I was sceptical when 747s were supposed to replaced BACs - but how on earth did you come up with ATRs replacing Concorde and A380? That was hilarious!

Happy birthday, and you're making fun of the forum I guess, but I am trying to see how can it be fun to do this this long

I can see it working, ATR seems more right-sized than A380 for Saskatoon.
