I might be wrong about this but last I checked new MBPs don't even have half of the maximum capacity that can be brought on a plane, because thinness curse. Edit: checked, and this was true for the 2016/17 models. The 2018 models have 58Wh (13") and 83Wh (15") in the most expensive configuration. 2016/17 models have 49Wh and 76Wh respectively. The non-touchbar ones have 54Wh, even in the 2018 models. You can take up to 100Wh on an airplane, not counting spares. So every MBP model currently available has significantly less than the maximum allowed capacity.
