I'm moving overseas and the airline has very strict luggage-weight limits, so I may have to put my GPU in a checked suitcase. I don't have the original packaging. Right now it's inside a large anti-static bag, covered with two or three layers of bubble wrap, and surrounded by soft clothing. Is there anything else I should do to protect it, or is checking it simply too risky? I'd rather sacrifice some clothes and carry it in my hand luggage if that's significantly safer.

Several people have transported graphics cards and other PC parts in checked luggage without problems, so it isn’t guaranteed to fail. The key is preventing movement and bending: use cardboard or a snug box, pad all sides, and keep it away from the suitcase edges. Security may open the bag and scan the component separately, which generally isn’t a problem.
Shipping it to your destination is another option, though that still involves rough handling. Properly boxed shipping may provide better rigid protection than a suitcase, but carrying it onboard remains the safest choice if you can make the weight work.
Carry it in your hand luggage if at all possible. Checked suitcases are dropped, stacked under heavy bags, and handled roughly, so a GPU can be damaged even if it’s well wrapped. Removing a few clothes is probably cheaper than replacing a 3070 Ti.
If it must go in the checked bag, add a rigid layer of protection. Put the anti-static and bubble-wrapped card between two pieces of sturdy cardboard, then surround it with clothes on every side. Pack the suitcase tightly enough that the card can’t move, but don’t put pressure directly on the fans or circuit board. A hard-sided suitcase would also help.

That was my concern too—shipping could also mean it gets thrown around. I may just move some clothes into the checked bag and take the GPU onboard.
