Cotopaxi Allpa 35L on JetBlue
Bag 20×12×10" vs sizer 22×14×9"

Tight Fit
Overhead Carry-On Verdict
Fits, if packed soft.
🎒 Backpacker's tip: The Cotopaxi Allpa 35L is soft-shell, so its depth runs ~1.5" over JetBlue's limit — but it squeezes into the metal sizer fine as long as you don't over-stuff the front pockets.
