The second last "mainline" A319 C-GBIA was flown to the desert 3 days ago... Flown on it twice in February and March, it was still in pretty decent shape. I'm surprised it's the one to go first. There's now only one remaining and according to the most recent MD&A, there will be one more A319 leaving the fleet this year, it's likely going to be C-FYKC next.
*We don't talk about the other two, we like to pretend they don't exist.
