Why this answer
Patagonia Black Hole Pack 25L is over the published personal-item dimensions, but the soft construction may make it a borderline option if lightly packed. Treat this as a fee-risk result.
The selected rule is 18 x 14 x 8 in and the bag record is 18.8 x 11 x 5.9 in.
Next step
Patagonia Black Hole Pack 25L is borderline for Frontier Airlines's personal item rule. Check the buying options only if the margin and packed-shape risk are acceptable.
