Question 1

Can I check this in at the airport as checked luggage?

Accepted Answer

I can't see why not.  I used these to send 50 lbs. of home cooked foods to my son in Colorado.  We live in Connecticut.  As long as you DO NOT have any hazardous materials in them, which by the way includes "dry ice," you shouldn't have any problem at all.  If you are using hazardous materials like dry ice, you need to fill out a form, which you can download from the airlines or shipping companies websites.   Cold packs are perfectly fine to ship via air, and they do not need any additional paperwork filled out. They also keep items colder for "longer" than dry ice. These containers exceeded my expectations.  They are durable, held far more than I ever expected to be able to get in them, sealed tight without any additional tape over the styrofoam coolers, and the corrugated box they come in is also durable, so the cooler fits snugly inside of them without any wiggle room.  My son received all of his food 2 1/2 days later (1/2 day late-Fed Ex), but it still had ice crystals in it, so these packs kept it really cold.  Hope this helps.

Question 2

What are the internal dimensions of the actual Styrofoam cooler?

Accepted Answer

12 W x18.5 L x15.5 H

Question 3

Could I ship spaghetti sauce across country in this?

Accepted Answer

This is quite large of a container. It will fit a good amount of sauce, depending on the size of the containers. But you have to also have room for freezer packs. As long as you have enough freezer packs in it, I don't see why you couldn't use it to ship the sauce.

Question 4

Will this hold 100 onces of frozen breast milk?

Accepted Answer

without a doubt.  this box is gigantic. i shipped 40 lbs. of frozen food in mine.
