Didn't realize that almost 30 years old,
pre-owned blue canvas/leather trimmed garment bag (carry-on in the DC-10 UA Friendship Service days) in good condition could still fetch some $$ on eBay these days. Haven't seen much use lately but still in excellent condition - checked it a few times, every other flyers had a garment bag in those days. It was light but sturdy and solid zippers/hardware.
