I'd imagine the logistics will be taken care of. I'd imagine they will mointor departures/ arrivals with a sophisticated FIDS (flight info display system) to make sure that passengers are met on-time.

Here's this scenario - you have 25 min connecting time - for instance your flight has arrived late into one of the big hubs, airlines don't serve food! What do you do?! It will be even worse if you travel cost to cost!!
