SWISSGEAR Softside Expandable Carry-On on Frontier Airlines

Bag 22×14.25×10.25" vs sizer 24×16×10"

≈ Tight Fit

Overhead Carry-On Verdict

Fits, if packed soft.

🎒 Backpacker's tip: The SWISSGEAR Softside Expandable Carry-On is soft-shell, so its depth runs ~1.5" over Frontier Airlines's limit — but it squeezes into the metal sizer fine as long as you don't over-stuff the front pockets.

The verdict, explained

At 22x14.25x10.25", the SWISSGEAR Softside Expandable Carry-On is over Frontier Airlines's 24x16x10" limit by 0.2" on its shortest side, but it is a soft-sided bag. Cinch the compression straps and avoid overstuffing the outer pockets and it will squeeze into the metal sizer; pack it bulging, though, and a gate agent may flag it. On Frontier Airlines: Personal item free; carry-on paid — gate price is the highest. It is too large for Frontier Airlines's under-seat personal-item space, so it has to go overhead or be checked.

💡 At the gate

Airlines measure at the widest external point — wheels, handles, and bulging pockets all count. Pull soft-bag compression straps fully tight before you size it.
