About 6 months ago I checked a DVD player. It was in its original packing, and I put it inside a duffel bag so that it wasn’t obvious what it was.
It arrived in perfect condition.
Of course, the DVD player had been sent from Amazon.com in the same packing, so if it survived that trip I don’t see why it wouldn’t survive my plane trip.
If it’s in the original box & packing I don’t think there’s too much to worry about. I don’t think sending it thru airline baggage is any harser than shipping it thru the mail.
I wouldn’t check anything that couldn’t live without if broken, and I wouldn’t carry anything on that I couldn’t live without if confiscated by some slope-browed screener. I’ve made both mistakes.
I’d suggest you mail it. Strange as it may seem, it is probably just a bit safer. I’d go for the insurance just the same.
I certainly can live without it, it’s just a 100 dollar model I’m giving as an xmas gift. If I have to, I can get another when at the destination, although it will be a bit after Christmas. If it’s only a bit safer shipping, I’ll check it in. My suitcase will give some added protection in addition to the manufacturer’s packing.
