Narrative:
I called in fatigued for my next trip. The schedules that are being created are approaching dangerous. After a 3-DAY trip; the first day of which we flew 8 hours 11 mins and ended up getting about 6 hours of sleep with 8 hours 49 mins of time off block-in to block-out. We stayed at a hotel we have never been to before due to overflow at our primaries; I assume. 13 days of work in a row away from home and 2 days at home in between. Speaking for myself; I would debate the safety of such a schedule. Consistent months built to 94 hours. I felt I needed to take matters into my own hands and take the time off. I feel I needed to be fresh to finish the next bunch of flying that I can never seem to modify.
