The US regularly moves military personnel and equipment to Europe straight from domestic bases via air. They can certainly reach Greenland as it is closer all while avoiding Canadian airspace.
Personally I believe if the US were to attack quickly it could successfully occupy Greenland in a matter of days. Leading to a very bloody drawn out war shorty thereafter.
If Denmark and it’s allies began increasing defenses now it would likely discourage the US or at the very least prevent a successful invasion.
Either way if deterrence fails there will be a very bloody conflict.
