At Alaska we have 11 hour long call with a 75 hour guarantee. They're on call 24 hours at a time. They can proffer trips in open time for the following day. Generally, they're used first and often.

Short call has a 2 hour call out with a 79 hour guarantee. They're on call 15 hours per day with "zones" having a start time from 3am (for early morning reports) till 7pm (for red eyes).

Each reserve line is scheduled to have two 48 hour breaks, one 72 hour break and one 120 hour break for a total of 12 days off. You can only be scheduled into one of your 48 breaks and the duty period that goes into your day off is paid at 250%.

We don't have airport standby.

LC's are used a lot more than SCs. In our LAX base, some SCs won't see a trip for weeks at a time when at the same time an LC hasn't had time to come up for air.
