"However, AC and Jetsgo were there for 5 hours before they were authorized to gio while WJ spent a little over an hour"
The difference is WJ has a maintenance base in YEG whereas JetsGo doesn't. In fact we pretty much have a maintenance base everywhere we go that can clear snags and MEL's whereas JetsGo has contract maintenance that can do walkarounds and basic maintenance. As far as AC goes, they may not have had maintenance engineers available in YEG that could clear that kind of problem (paperwork issues). So before spouting off about WestJet not clearing the fuel and taking off, get the facts straight. I could ask you what your completion rates are for flights or how many MEL's you carry around but I've only heard second hand that your maintenance is scary, so I won't mention it. Oh wait, now that I've said it, it must be true.
