Amazon Basics Hardside 30"
$40 under your budget

■ The catch — co-equal billing, always
ABS is the cheapest shell for a reason. It scratches and cracks faster than polypropylene or polycarbonate, and the warranty is barebones — cross 6 trips a year and it won't keep up. This is an occasional-use bag, full stop.
Dealbreaker? Runner-up №1 (Samsonite Freeform) upgrades the shell for ~$59 more ↓

Oversize fees
Airlines cap checked bags at 62 linear inches and 50 lbs — go over and you pay $50-$200 per bag, every leg. A 30-inch shell can blow past 62 inches once packed, so size to the ceiling, not the raw capacity.
Phantom capacity
Manufacturer liters are aspirational. Outdoor Gear Lab measured the category's top pick at 128.8L against a claimed 143.5L — treat brand numbers as ~15% high and pack against tested volume.
Full-price timing
Checked luggage goes on deep sale predictably. Prime Day and Black Friday cut prices 30-50%, so buying a $400 bag at full MSRP in a dead window is the easiest overpay to avoid.
