I have taken Southwest Airlines with my BVM Electra in the Jet case it was very bulky and won't fit on most carts and the guys at South West scratched up the case a lot. Make sure you label it fragile and do not drop. I would suggest that you get to the airport very early because I am certain that security will want to have a look inside. If it is a turbine jet make sure their is no fuel at all in the aircraft and you will probably have to pull the lithium packs out as well. I would do it again but only as a last resort.
