Cabin, if space
Allowed as a paid carry-on under the federal rule if there is bin space when you board.
Ask the airline whether it can have a seat.
At the airport, call it a violin. Few staff know what a viola is, and some picture a cello.

Frontier rules
- Frontier accepts instruments and groups them with special, oversized or fragile items that may need special handling.
- Its FAQ gives no cabin sizes or seat rule and points to a Special and Fragile Items document.
- As a US carrier Frontier is bound by the federal rule: a small instrument is accepted as carry-on if it can be stowed and there is space.
- Frontier charges for carry-on bags, and that standard fee applies to an instrument.

Before you leave for the airport
- Measure the case and weigh it packed. Staff measure the case, never the instrument.
- Check the fare. The cheapest fares often include only an under-seat bag.
- Check who operates each leg. The operating airline's rule applies.
- A seat for the instrument is booked by phone, often 48 hours or more ahead.
- Photograph the instrument and case before you leave home.
- Board as early as you can.
