A red arrow day is just a "smoke signal" for us to know that hey are at or near the minimum reserver coverage for that day. I have had about 85% of my swaps approved, even with the red arrow day. On most, I have had to make multiple submissions.
I do not expect them to ever staff this airline to cover unlimited pilot swaps--nor would I want them to. Reserve staffing has to be managed properly to keep staffing levels and costs down. The main objective is to cover forecasted sick calls and IROP conditions. I have not been extended or drafted in years--that's what most pilots should care about. Unlimited swapping could never be achieved without affecting other pilots that hold lines. I have a job with a company that still makes money--that's how I want to keep it!
You still have a ways to go. Comair is so understaffed that every reservist gets used nearly every day. You are always extended to where you never expect to go home after a trip. It is now the norm that you can also expect to have your days off changed somewhere in the month. Some of our reserve guys are actually flying more than our line holders. There is something wrong when the reserve guys are getting 90 hours of credit each month.
