For anyone still thinking about coming to QX, keep in mind that this "staffing problem" is 100% the fault of Air Group and Horizon management being unable to see further than the next quarter into the future.
The 8 year contract that created this entire problem was something that Air Group was adamant they had to have in order to "commit to compete" during Shiny Jet negotiations, and that's exactly what they ended up getting.
Less than a month after that contract was signed, the industry standard for FO compensation had jumped to around $20-30k more than QX pays (although the trend was clear before the deal was signed), and management absolutely refuses to admit that this situation is anything but the fault of those darn greedy pilots.
