FWIW
i have used a Thule ski case and bubble pack, although at some US airlines & air freight will not take them due to the fact they have had gas(jet a) in the systems.. per FAA Regulation.... Had problems with SW ,USAir , No problem with Delta( had FAA Reg posted on wall but I guess no one read it), They must inspect the case befor excepting it for shipment
Good luck, see you at Florida Jets
