Point of order:
10 lieu days (for missed bank holidays) or as we call them 2 x Duty Free Weeks.
Duty Free Weeks (for a full-time pilot) are 2 x 7 day blocks plus a non-assignable day so up to sixteen days off annually, one DFW per season.
This gives a total of 42 leave/DFW days per year plus two Non-assignable days (with DFW) and four "wrap days" per week of leave. Overall, 60 days off associated with leave or DFW. All DFW and leave days have credit hours attached (a matter of opinion whether you consider this credit to be sufficient - most don't), NA and wrap days do not.
