The current generation "Cabin" sizes are mostly in excess of what domestic carriers permit.
However, so long as you aren't travelling on a budget carrier, last boarding group or regional aircraft, your likelihood of being able to carry the current generation "Cabin" on-board is still likely.
The previous generation "Cabin" sizes were 32L in volume, a guaranteed fit for most domestic carriers, as the dimensions were IATA-compatible.
The current generation"Cabin" sizes are 36L in volume, a guarantee the trolleys now, exceed most carrier carry-on limits.
