I wouldn't be concerned over one turn canceling at all. In fact, other DCI carriers cancel more often and are less reliable - they don't even worry about losing their feed. Nobody else is staffed to take the flying anyway. Everything is going to be ok.
If they were really desperate, they would make Critical Pay a higher percentage.
Now let's talk about something exciting!!!
Since the current vacancy is only for FOs, will they backfill an FO position if a DTW or MSP a FO moves to LAX?
When is the next CA upgrade vacancy coming?
