Not sure this will be true. Relatively close commuters maybe...

As it's currently written, I believe it's a 12 hour call out regardless of report time.

I.E. 8pm call on Tuesday night for 8am report Wednesday morning. In many cases, 8pm is either past the last flight of the night into the hub or darn close considering you need to grab your bag and be out the door and at the airport before that last flight and could likely be before the first flight in the AM will get you into the hub.

Especially true if you commute across timezones where you lose time into the hub.

So LCR as currently written is probably best for something like Boston commuters into NYC. For that, it's great.

For something like a MEM to ATL commuter, not so much.
