Buying 2 pairs for long airplane trip. Should I store them in a special container (tupperware)? Would they break inside our carry-on if unprotected?

They are strong enough for a carry-on, but not strong enough if stepped on.

They were fine for us on a few trips. Eventually the part with a couple screws that attaches the earpiece to the headband will break.

My personal experience is that if you refrigerate them overnight and THEN freeze, they do not break. If you put room temp foods (leftovers or something) in them and put them straight into the freezer, then they DO break. Even if you give them space to expand.

The bags are airtight, but with changing air pressure the bag may not make it. So I wouldn't recommend bringing in my suitcase.

I buy them in advance. They are sealed in a bag, so they will last a long time. If you use them only at certain times, store in a baggie.I just change mine every 30 day after constant wearing.

They fit secure in the tray. A perfect fit. The lids are very secure I would be surprised if they opened up. But if your saying would the individual days come out of tray. Well it all depends. Is the suitcase stuffed where they would not have room to wonder? They aren't glued in tray but fit perfect. We never even bring the tray we just bring the individual days we need. I like packing light light. So I can't answer the question fly all over, that hasn't been the case with us at all.

The box they come in is very sturdy and has foam cut to shape. It isn't convenient for a road trip but if you wanted to fly and take carry them in your luggage it would be adequate.

Unless you use them regularly, they may lose moisture. I keep mine in a Zip bag.

They get hard but they do flex due to the "quilted" design, not quite foldable though. I purchased for airline travel myself, checked baggage and no problems- not sure if they would fly as carry on as they are a "liquid/gel" when thawed which would be over the 4oz limitation. Hope that helps!

I've been using them for a good while which I think is long term and so far I haven't had any problems with them. But no they aren't air tight. To make them so I would cover them with plastic wrap before putting on the cover or just find an alternative container.

I tried to take similar packs in my carry-on and they were confiscated by security. Pack them in your checked bags and you'll be okay.

I just ordered a pair and will be using them for a my flight Orlando -> LAX -> Sydney at the end of August. I'll let you know how it goes.

The lids are actually almost a too snug, so it's doubtful the contents would spill during transit. But they may vary from one set to the next, so you would probably want to use a bit of scotch tape just to be sure.

Best to store them in zip lock or in container with good fitting lid. Store in cool, dry place.

As long as not carry on it should be fine. But I have never traveled with these on an airplane.

I carried them in my bag from Nebraska to Africa with no problem. Good luck!

I am not a TSA officer, so I'm not sure. They aren't weapons, but I would put them in my checked bags rather than carry-on. Just in case.

I can't answer with any authority, but something is better than nothing. You can pack them really well, maybe in a plastic ziplock and bury it in the deepest part of your back pack. If these are working for you, then definitely YES, take them and take care of them. Hope this helps with the decision making. Enjoy your backpacking trip!~nanette
