Frontier Airlines: flying with a musical instrument
Frontier, an ultra-low-cost carrier, allows small instruments in the bin but directs large instruments to checked cargo with no published extra-seat option.
Cabin / carry-on
Small instruments allowed if they fit in the overhead bin.
Extra seat
Frontier's published Special & Fragile Items policy does not describe an extra-seat option; large instruments that do not fit the overhead bin must be checked into the cargo hold. The federal statute's extra-seat right may still apply — confirm with the airline.
Checked
Large instruments must be checked as cargo; the PDF states a 100 lb cap for such items.

Per instrument
How each instrument fares on Frontier Airlines
| Instrument | Verdict | What it means |
|---|---|---|
| 61-key portable keyboard | Gate-check risk | A 61-key portable keyboard in its case often fits a mainline overhead bin but is a real gate-check risk on full flights and regional jets. Board early; if the bin is full it may be gate-checked. |
| Alto saxophone | Cabin likely | A alto saxophone in its case is small enough to stow in an overhead bin or under the seat. US federal law (49 U.S.C. §41724) gives you the right to carry it on if it fits and space is available at boarding. |
| Banjo | Gate-check risk | A banjo in its case often fits a mainline overhead bin but is a real gate-check risk on full flights and regional jets. Board early; if the bin is full it may be gate-checked. |
| Cello (4/4) | Checked only | A cello (4/4) is too large for an overhead bin and Frontier Airlines publishes no cabin-seat option, so the published path is checked/cargo. The federal extra-seat right may still apply — confirm with the airline. |
| Dreadnought acoustic guitar | Gate-check risk | A dreadnought acoustic guitar in its case often fits a mainline overhead bin but is a real gate-check risk on full flights and regional jets. Board early; if the bin is full it may be gate-checked. |
| Electric guitar (gig bag) | Gate-check risk | A electric guitar (gig bag) in its case often fits a mainline overhead bin but is a real gate-check risk on full flights and regional jets. Board early; if the bin is full it may be gate-checked. |
| Parlor / travel acoustic guitar | Gate-check risk | A parlor / travel acoustic guitar in its case often fits a mainline overhead bin but is a real gate-check risk on full flights and regional jets. Board early; if the bin is full it may be gate-checked. |
| Trumpet | Cabin likely | A trumpet in its case is small enough to stow in an overhead bin or under the seat. US federal law (49 U.S.C. §41724) gives you the right to carry it on if it fits and space is available at boarding. |
| Ukulele (concert) | Cabin likely | A ukulele (concert) in its case is small enough to stow in an overhead bin or under the seat. US federal law (49 U.S.C. §41724) gives you the right to carry it on if it fits and space is available at boarding. |
| Viola | Gate-check risk | A viola in its case often fits a mainline overhead bin but is a real gate-check risk on full flights and regional jets. Board early; if the bin is full it may be gate-checked. |
| Violin (4/4) | Cabin likely | A violin (4/4) in its case is small enough to stow in an overhead bin or under the seat. US federal law (49 U.S.C. §41724) gives you the right to carry it on if it fits and space is available at boarding. |
