I need to bring an 8 oz bottle since I'm unsure how available it will be in a small town in Guatemala and I'm gone 4 wks. I've read repeatedly that TSA will allow a larger bottle of lens solution as it's medically necessary, however, I've read older posts (2007) that state TSA agents are inconsistent and will sometimes throw out multi-purpose solutions (vs saline which is explicitly allowed -- but saline isn't a disinfectant and must be used with a heat device).

I've never tried to bring in a large bottle of multipurpose lens solution -- recent feedback would be appreciated -- flying out of ORD. tia!

I'd just take 3 containers of <3 ounces in your ziplock bag if you're not sure. It's easy to buy things like shampoo and toothpaste down there so I use my ziplock for 1st aid stuff and great quality sunblock and bug stuff, sometimes more than one container each depending on the length of my trip.

ha, my answer would be the same as above!

I can fit a lot in a ziplock!

make that 3 votes! Just put the solution into several 3.4 oz bottles which will be in your 1-qt allowable ziplock baggie.

or check a bag.

Have you seen this...it talks about special family and medical lanes.

Lost a Pepto bottle recently that was just a bit too big

so divide and conquer for me in 2 3 oz bottles to be safe.
