BAM flight cover more affordable, though not 100% guarantee

Flying with Your Cello
The cello case options mentioned above will definitely withstand a lot of walking around andtraveling by car. But what if you have to fly somewhere with your cello? You will want to consider getting a dedicated cello “flight case.”
There are a couple options:
1. You could either purchase a flight case that’s intended to protect your instrument if you check it, or you could purchase a cello case flight cover. If you purchase a flight case, it will likely be really heavy but that’s because it’s meant to withstand the rigors of touring, rough handling, and being checked underneath the plane (with the passenger luggage). They’re usually made from durable Kevlar and fiberglass.
Pros: You won’t have to buy an extra seat or deal with the hassle with the airline.
Cons: No case will ever fully protect or 100% guarantee against super rough handling by an airline employee, and you might worry that the cello will be in one piece when it arrives at its destination. Also they can be costly.
2. If you’re going to choose to fly with your cello and you own a Bam case, there is an option now to cover your cello case with a Bam cello case flight cover in order to protect it when it’s checked as baggage. This flight case cover is a thick cordura cover with approximately 2 inches of insulating polyurethane foam. This is an indispensable addition to the Bam cello case for travel. The cover is molded to fit most Bam cases (Light, Flight, American, Shuttle, Voyager and Newtech models). The cover may fit other brands of cello cases but we cannot recommend its efficiency when used with non-Bam cases. If you end up purchasing one of these Bam case flight covers, here’s a little trick we found on the Bam website: “Fit the cello case, head first in the Flight Cover, zip around the head, adjust the bottom of the case inside the Flight Cover and zip around the bottom part, the zipper pulls meet in the middle.”

Pros: Very protective. You won’t have to buy an extra seat or deal with the airline. More affordable than a “flight case.”

Cons: No case or case cover can ever fully protect against super rough handling or bouncing in checked baggage, and temperature could also be a concern if you’re checking your instrument.
