There's a nuance though... in the current era, reserve call-out times are getting longer, in some cases with language or an understanding of "get there as soon as you can".

If everybody takes it to the contractual max, then something will eventually have to give as the company will act to ensure operational reliability... whether that's hot reserve or shorter call-outs we don't know.

There's such a thing as enlightened self-interest. I won't rush, drive 95mph, etc. I might not even cut my workout short. But if I'm sitting around doing not much, then I'd probably head on in. Especially if it's late, no need to keep the pax, crew, and myself up any later than necessary on the back end.

Something to think about.
