Google Flights will allow you to select how many carry-ons and checked bags you have (depending on the route).

e.g., on an imaginary trip to Las Vegas, the cheapest carrier changed when I added a checked and carry on bag (and the price difference from a budget carrier to a mainline carrier shrunk considerably).

Sure, but I've not seen them offer tick boxes for things like the ability to choose which seat you're in, or complimentary snacks and drinks.

ZipAir doesn't even provide free cups of water during its flights. They require all baggage, even carry-on, to be under a certain weight or pay an additional charge.

Unbundled options is no longer merely about how many bags you check or carry on. They're monetizing _everything_.
