Per instrument
How each instrument fares on JetBlue
| 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) | Extra seat | A cello (4/4) is too large for an overhead bin. On JetBlue the standard path is a purchased extra seat (the statute's cabin-carriage right, up to 165 lb, where the airline sells one) — see the airline's seat-position and weight rules. It may also be checked within the 150-linear-inch limit. |
| 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. |
