One note is that this plane was leased to WestJet for two years, between 2000 and 2002. The harsh winter weather in Canada, combined with the humid heat of Florida would also have increased the environmental factors that increase maintenance requirements.
Lolwut? Man, I need to stop reading simpleflying.com They are terrible.
Plenty of aircraft based in North America constantly fly from the Deep South (South America) to Canada, to Hawaii, to all points in between and don't have "environmental factors".
Get out of here with this shit, SimpleFlying.
P.S. yes, extreme cold is a bitch. -40°c wrecks tires and other stuff. Not applicable 20+ years and multiple heavy checks later.
