Bernard,
It is not airport employees that make those decisions for the most part. But just like any other walk in life, ...put a badge and/or uniform on some people and they are tempted to be cops. In the past, airlines and their Air Transport Association (ATA) guidelines have been to allow just about anything in the cabin that would not impose upon other passengers or safety. But now, the Cops in the white house are calling the shots about most everything that gets scrutinized going into the cabin of airliners; And even the airlines, ATA and gov't are just now beginning to reach some agreements for the left hand knowing what the right hand is doing. So it looks like for the time-being, the least you have to carry on the better.
Because other overhead baggage is likely to be thrown in on top of an instrument, it is best to use a hardshell case. Duct tape or nylon belts all the way around the case to secure the latches is also recommended.
I'm sorry but I do not recall the Standard dimensions of overhead bins ...nor even if there is one. I would imagine that is something the Union in
Cindy Cashdollar's posting mentioned here earlier, could provide that info.
It is always a good idea to call your airline and ask them what their carry-on policy is for number of bags, sizes, weights etc. This will become more important in the near future. Following a recent commuter airline fatal accident, studies have supported previous studies and complaints from the pilots and flight attendants unions that the ATA / airlines have been grossly underestimating the number and weight of carry-on bags AND the weight of passengers ... which have been overloading full airplanes. This translates into reducing the number of passengers / $tickets ... or reducing the number of carry ons. It's pretty obvious which one they're going to reduce!
Here are some additional tips: ALWAYS BE A NICE GUY/GAL; You're at their mercy. If you get your instrument on the airplane and find there is not enough overhead storage for your comfort about your instrument, there are other legal places to store them: Behind the last row of seats in just about any airliner. In larger airliners with cabin divider bulkheads, behind the last row of seats in front of each bulkhead; And larger airliners also have at least coat closets, and real large airliners a number of unadvertised closets that the flight attendants have full authority over and will usually put things in if they aren't appropriate for the overhead (an humble / kind explanation of the instrument's delicacy to most flight attendants can make it "unappropriate" for the overhead). THEY HAVE THE LAST SAY; The closets ARE NOT an automatic passenger entitlement.
Aloha,
DT~
