At Spirit, you can drop all your trips and get 31 days off. You won’t make any money that way though.
For simplicity’s sake, you can reasonably expect to get 5 hours of pay per day of work. Do the math with Spirit’s pay scale to see if that’s a good balance of pay and time off for you.
Also keep in mind that you have to put up with a variable period of reserve where you can’t drop reserve days. You will get 12 days off in a 30 day bid period those months and 13 off in a 31 day bid period, with a 72 hour guarantee.
