I've spent far too much of my life in the air, if you have time, then check a bag. If your a frequent flier, and want to avoid the bag pick up then its a separate set of rules. Easiest way to de stress flight, show up early and take your time. I prefer window seats to throw in the earbuds and crash. If you plan to carry on, then 3 oz liquids in a 1 gallon bag is the rule. I carry a split backpack that folds, so I do not have to pull the laptop out. I personally would not check a PC, but even when I carry it on, I rarely take it out during flight. Do not be in a hurry, and be nice. It always works for me, other passengers do not get there any faster. Good luck and safe travels.
