Hey folks! I'm doing a lot of flying this year, and am checking my Kent McLagan bass (w/ removable neck) into a Lemur flyaway case and floating all around the country. So I compiled this list to know what each airline says about their baggage allowances and musical instruments. Please feel free to add corrections, or add information from other airlines, or experiences/nightmares of flying.
American Airlines:
Your musical instrument can also be checked as baggage. The maximum size for checked baggage, including instruments, is 150 inches (381 cm), and the maximum weight is 165 lbs. (75 kg).

JetBlue
A musical instrument will count as one piece of checked baggage. There are no additional fees for musical instruments as long as they do not exceed 150 linear inches or 165 pounds (75 kg) or the applicable size or weight restrictions for the aircraft(overweight, oversize and excess baggage fees will apply). JetBlue accepts no liability for damage to musical instruments. We suggest packing them in a hard-sided container designed for travel.

Southwest
Some musical instruments (e.g. double bass, cello, etc.) cannot be secured in a seat and must be transported as checked baggage. Oversize or overweight charges will apply if the instrument is between 62-150 inches in size (outside length plus width plus height including case or covering) or if the instrument weighs between 51-165 pounds (including case or covering).
-Overweight Charge (more than 50 lbs): $75

United
An instrument should be packed in a hard-shell case to keep it protected during normal handling. Excess checked baggage service charges may apply if the customer is checking more than two items. Oversize charges apply to musical instruments that measure 63 - 115 linear inches. Overweight charges apply to musical instruments that are over 50 pounds, but musical instruments weighing up to 165 pounds will be accepted. If the instrument is over 115 linear inches, please contact the United Customer Contact Center.
-Overweight Charge (more than 50 lbs): $100
-Oversize Charge (63-150 linear inches): $200
Virgin America
If it exceeds the hand baggage allowance measurements, you’ll need to check it in (and pay an additional baggage fee, if it takes you over your check in allowance). However, rather than checking it in on the spot we’ll still ask you to carry it through to the airport security checkpoint (subject to relevant Airport Security approval). As instruments are especially fragile, this ensures safer carriage. It will be taken at the departure gate for loading into the hold of the aircraft, so please make sure it’s suitably protected when you pack it. The upper limit for oversized luggage is an ample (75 x 29.5 x 25.5in)
-Overweight Charge (23-32 kg): $60
-Oversize Charge (more than 63 linear inches): $60
